How to load Linux Kernel and files system with no Ethernet port

Added by Vivek Ponnani over 3 years ago

Hi,

I have a custom board with
1) MityDspl-138F module (with FPGA)
2) No Ethernet port
3) UART,USB,SD CARD interface

I have built VM with MityDSP-L138_SDK_2012_06_13.ova file from critical link.

I connect the board with serial port xds200 JTAG emulator. I use teraterm application from windows with 1115200 baud to receive information from the board. when I power on the board,I get following info (MityDspl-138 Uboot.txt).

OMAP-L138/AM-1808/AM-1810 initialization passed!

I understand that I have to load Linux kernal and .jffs2 file systems on board with SD card interface.Followings are my questions.

1) Can anyone explain me how to load Linux kernal and .jffs2 file systems on board with SD card interface from Linux or Windows.
2) In Linux VM (MityDSP-L138 SDK) which serial port communication application I can use to communicate with board?
3) I have connected test LEDs at GP01 and GP04 on my board for test purpose.Is there any way that without loading kernel and filesystem,I can toggle test LEDs on my board with CCS.

Thanks.

Did you take a look at the section "Booting off MMC / SD Card" in the Linux Root File System page?

This describes loading images from SD. It requires the u-Boot is properly built with MMC card support.

You can load the .jffs2 files and program the NAND this way, or you can simply boot from MMC and skip the NAND if that makes sense for your application.

There are a number of serial port programs. For linux or windows you can use putty. If you want a terminal based serial program look at minicom.

3) I have connected test LEDs at GP01 and GP04 on my board for test purpose.Is there any way that without loading kernel and filesystem,I can toggle test LEDs on my board with CCS.

First you can toggle LEDs in u-boot by writing to the correct memory registers. You could do the same thing from a debug session using CCS.
  • Look up the GPIO memory address in the L138 datasheet
    http://www.ti.com/lit/ds/symlink/omap-l138.pdf
    Page 23, Table 3-4
    GPIO base address is x01E26000
  • Next we look at the OMAP-L1x Processor General-Purpose Input/Output (GPIO) Users Guide. It tells us what the register offsets are for configuring the gpio.
    http://www.ti.com/lit/ug/sprufl8b/sprufl8b.pdf
    page 18, chapter 3 registers
  • Also read chapters 2.5, 2.6, and 2.7 of the gpio guide for how to use the gpio registers
  • You may also need to update the pinmux registers for the pins you are using so they are set as gpio. The pinmux register addresses can be found in the syscfg table 4-1 page 74 in the l138 datasheet mentioned above. To determine which pinmux register you need to update, you need to look at the L138 TRM (http://www.ti.com/lit/ug/spruh77c/spruh77c.pdf) page 236 1.5.11 Pin Multiplexing Control Registers (PINMUX0-PINMUX19)

Hi Mike,

Thanks for your response.

1)First of all, when I start VM, I get that "your Ubuntu release is not supported anymore". I have attached screenshot for it. (Screenshot.png)
It seems because of it I am not able to process further for any update required.
I have MDK_2014-01-13 environment.Is it possible to upgrade Ubuntu from 10.04 to 14.04 for MDK_2014-01-13? Do you have any .ova image which supports Ubuntu 14.04 for mitydspl-138f?

2) I was following section "Booting off MMC / SD Card" in the Linux Root File System page, but when I insert the MMC card on target and checked with mount command, It gives response as below (mount.txt)

mitydsp@mitydsp-dev:~$ mount
/dev/sda1 on / type ext4 (rw,errors=remount-ro)
proc on /proc type proc (rw,noexec,nosuid,nodev)
none on /sys type sysfs (rw,noexec,nosuid,nodev)

3)Then if we process further with command sudo -s and unmount /media/mmcblk0p1, it gives response as below (prepare_SD_Card.txt)

mitydsp@mitydsp-dev:~$ sudo -s
[sudo] password for mitydsp:
root@mitydsp-dev:~# unmount /media/mmcblk0p1
No command 'unmount' found, did you mean:
Command 'umount' from package 'mount' (main)
Command 'umount' from package 'loop-aes-utils' (universe)
unmount: command not found

4) Then I follow Exporting as NFS mountable drive, but it seems as there is no more support for Ubuntu 10.04, when I run
sudo apt‐get install nfs‐kernel‐server, It gives response as below(Install_nfs_kernel_server.txt)

RE: How to load Linux Kernel and files system with no Ethernet port - Added by Jonathan Cormier over 3 years ago

Vivek, Sorry about all this. The apt-get repo's got moved when it went end of life. We've been meaning to post a new VM but things always come up. If your up for it, you can install ubuntu 14.04 or 16.04 in a VM then install the toolchain from https://support.criticallink.com/redmine/projects/arm9-platforms/wiki/GCC_Toolchain and the MDK https://support.criticallink.com/redmine/projects/arm9-platforms/wiki/Updating_devkit_to_latest_MDK

I'll ask around to find out where the update VM project got to.

RE: How to load Linux Kernel and files system with no Ethernet port - Added by Jonathan Cormier over 3 years ago

Uploaded newer VM. This one is based on Ubuntu 14.04. Note this VM has both 335x and L138 toolchains.

Is there any missing part, which I should follow before installing Putty or minicom?

Also in this version of Ubuntu, I can not find any software center option where I can find softwares to install.

Please suggest further action.

Network is unreachable

Looks like you don't have internet in the VM. When you started the VM did it ask you about specifying your computers network adapter. You can use 'ifconfig' in the VM to print the network adapter information. Paste the output here if you can't get the network adapter working.
https://www.thomas-krenn.com/en/wiki/Network_Configuration_in_VirtualBox
You want bridged networking.

Nope assuming you get internet to the VM, apt-get will install everything you need.

Also in this version of Ubuntu, I can not find any software center option where I can find softwares to install.

Hmm this was a custom install of Ubuntu. Looks like we forgot the software center. Most of us use apt-get to install everything.

Note that the nfs server would be used for a network boot. Since you have no ethernet on your board, this won't be needed.

Hi Jonathan,

Sorry for the late response.
Thanks for your guidance.
You were right, I was not able to connect to network. From the links you provided, I managed to get network by changing setting for Network-> Advanced->Promiscuous mode from Deny to allow all in VM.
I managed to get serial connection with putty and minicom as well.Now , I am trying to make SD card with Linux root file system and uImage. For that I followed Booting off MMC / SD Card in Linux Root file system. It is mentioned that, "you need to prepare the SD card. This can be done on the target by inserting the MMC card and running the commands:".
As I mentioned earlier, I have no Ethernet port. With serial port, I am not able to see card on the target from VM. How could I prepare the SD card?
I tried to do it from VM by inserting card on host machine as following.. but no success. (Prepare_SD_Card.txt)

You shouldn't need Promiscuous mode. This mode is usually used to packet sniff a network. It tells your network card to not filter packets destined to other computers.

In modern linux, you should never have to create a file or folder in the /dev/ directory. uDev or the systemd alternative is responsible for creating files in this directory.

root@vagrantup:/# umount /media/mitydsp/E4DE-5094
root@vagrantup:/# mke2fs -j /dev/E4DE-5094
mke2fs 1.42.9 (4-Feb-2014)
/dev/E4DE-5094 is not a block special device.
Proceed anyway? (y,n) y
mke2fs: Device size reported to be zero. Invalid partition specified, or
partition table wasn't reread after running fdisk, due to
a modified partition being busy and in use. You may need to reboot
to re-read your partition table.

This is because you created a folder and are trying to treat it as if it was a block device.

root@vagrantup:/# mount /dev/E4DE-5094 /media/mitydsp/E4DE-5094
mount: mount point /media/mitydsp/E4DE-5094 does not exist

Is there any other method to prepare SD card with serial port?, please suggest.

When you insert the sd card into your computer, assuming you are using a USB to SD card reader, you need to go to Devices -> USB and select your sd card reader to be mounted in the linux VM. When the sd card is inserted into the reader, linux should assign it a /dev/sd* block device. /dev/sda is usually going to be the computers harddrive and this is true for the Unified VM.
  • In terminal, run sudo fdisk -l. This will list all the storage devices linux detects.
    Below you can see the VM's hard drive at /dev/sda and its partitions. Next you will see some /dev/mapper disks, these are for Linux LVM and can be ignored for this. At the bottom you can see /dev/sdd which is my inserted sd card. I can be pretty confident that the disk is the sd card by looking at its total size (3965 MB), this closely matches the 4GB sd card.
    Note that the main parition on the disk is /dev/sdd1 and this is were we want to format as ext.

Hi Jonathan,

Your guidance is really helpful. I am able to load Linux Kernel and files system on SD card and boot from it. Now, I am trying to setup hello world application in VM ( Critical_Link_Unified_VM_14-04_04-2017.OVA) which has Eclipse 3.8.1 and CCS 6.1.3.00033 installed. When I opened these applications for the first time, it starts Install updates. It is not able to install updates in both applications(Eclipse and CCS) as it is giving some errors. Attaching some snapshots for errors. Should I continue to develop Hello world application without installing updates? I am following the links as below for hello world application.

1. https://support.criticallink.com/redmine/projects/arm9-platforms/wiki/Starter_Guide
2. https://support.criticallink.com/redmine/projects/arm9-platforms/wiki/DSP_Hello_World

Please let me know if there are any updated links for new VM (Critical_Link_Unified_VM_14-04_04-2017.OVA).

Thanks.

RE: How to load Linux Kernel and files system with no Ethernet port - Added by Jonathan Cormier over 3 years ago

Vivek, Looks like there is a bug with the VM that is breaking internet.

  • Open Terminal
  • sudo vim /etc/network/interfaces
  • Delete the below lines and save the file
    #VAGRANT-BEGIN
    # The contents below are automatically generated by Vagrant. Do not modify.
    auto eth1
    iface eth1 inet dhcp
        post-up route del default dev $IFACE || true
    #VAGRANT-END
    
  • Reboot

I'm sorry for the trouble. It looks like TI dropped support for dsp bios in CCS v6. Our instructions are all written for CCSv5.5. I'm currently reworking some of our instructions. I'll let you know in a bit when i'm done. For now you can start by downloading and installing CCSv5.5. https://support.criticallink.com/redmine/projects/arm9-platforms/wiki/Installing_CCS5_for_L138_DSP#section-4

Note: You can build both the ARM and DSP parts in CCSv5.5. No need to do the ARM in eclipse and DSP in CCS.

RE: How to load Linux Kernel and files system with no Ethernet port - Added by Jonathan Cormier over 3 years ago

Okay I was able to successfully install CCSv5.5 in the VM and follow the Starter Guide and DSP Hello World. Let me know if you run into any problems.

Doesn't look like you did anything wrong. I never tried the install with the proceeding '&' but i'd be surprised if thats the problem.

I guess try it without the '&', though i can't explain why that would break anything.

No they will both live happily next to each other. I ran through all the steps on the same VM you have so I'm a bit confused. What doesn't make sense is this line which you shouldn't get if you are running via the terminal inside the VM.

Hi Jonathan,

It seems the first command of install Prereqs (sudo apt-get install libgnomeui-0 libusb-1.0-0-dev ) didn't work well in my first installation(may be due to momentarily disruption of net connection). I did all the process all over again and I am able to install CCSv5. I am attaching both files for Install prereqs. commands, for old installtion(Install_prereq_old.txt) and new installation (Install_prereq_new.txt) for your reference.
Now, I am able to execute the helloworld application for both ARM and DSP. As I was following the link https://support.criticallink.com/redmine/projects/arm9-platforms/wiki/Starter_Guide, It shows how to load application image to board with ehernet port.

1)I tried following commands on board.

root@mityomap# opkg update
root@mityomap# opkg install libstdc++6

For the first command it is giving errors, as I have no Ethernet port. For the second command it gives response "libstdc++6 is up to date"
I hope this would be fine.

2) Will scp work over serial connection? If no, please suggest how to load application image to board with serial port.

Thanks.
-Vivek.

RE: How to load Linux Kernel and files system with no Ethernet port - Added by Jonathan Cormier over 3 years ago

I've not really tried to send files over the terminal. But it should be possible using xmodem. The L138 filesystem has the rx program which is used to receive xmodem file streams. sx would be used on the other side. I'm not sure exactly how to run these commands though to get them working.

https://www.systutorials.com/docs/linux/man/1-sz/

Do you have an sd card slot which you could use to transfer files? Or usb?
