- GG 06:06 PM Software Development: RE: uPP on MityDsp
- Hi Martin,
LCD [8] - LCD [15] also function as Boot Mode Selection pins. The SN54LVC157A is used to change the pull-up/pull-down configuration to allow for different boot modes.
Once the system is booted these pins can be reconfi... - MH 04:27 PM Software Development: RE: uPP on MityDsp
- Hello Greg,
many thanks for your answer.
as i Know LCD[x] pins are outputs. and on the MityDsp is see U9 which is a SN54LVC157A multiplexer.
We also see some 2k Resistors to GND in these lines. (R54-R62).
Thats why I ask if these Sig... - GG 04:05 PM Software Development: RE: uPP on MityDsp
- Hi Martin,
I have never personally used the uPP in this setup, however, it looks like it should be possible.
For hardware details please refer to http://www.criticallink.com/wp-content/uploads/2014/01/MityDSP-L138-Carrier-Board-D... - I have a question for clarification.
We want to use MityDsp without FPGA and use both uPP-Channels as Input.
Is that possible?
Thanks in advance for answers.

- JC 03:18 PM Software Development: RE: IPC and uPP interrupts APIs conflict
- Hi Okan,
I'm not too familiar with either syslink or starterware. However I've found that when I'm debugging kernel problems similar to this and I don't know where to go, I try to dump as many registers as I can to a text file when th... - OÇ 12:42 PM Software Development: RE: IPC and uPP interrupts APIs conflict
- Hi Greg,
I've already read the relevant sections of the technical reference manual and megamodule reference guide, but I still have no idea how the Notify module initializes its interrupts. The function @Notify_registerEventSingle()@ ...

- GG 04:03 PM Software Development: RE: IPC and uPP interrupts APIs conflict
- Hi Okan,
My guess is that your core problem is that SysLink and StarterWare simply do not play well together in general. My understanding of StarterWare is that it is intended as a means for the DSP to run independently. Therefore, d... - OÇ 05:51 AM Software Development: RE: IPC and uPP interrupts APIs conflict
- Hello again,
I've just realized the line "@ISTP = (unsigned int)_intcVectorTable;@" in @{StarterWare}/system_config/c674x/interrupt.c@ appears to be what breaks the Notify module. The symbol @_intcVectorTable@ is defined in @{StarterW...

- JC 02:07 PM Software Development: RE: Linux USB Gadget is not working on custom board
- Glad it worked. I suspect your ID pin is being pulled low somehow. But as long as you don't need to support HOST mode, there should be no problem with forcing Peripheral mode.

That actually worked. Thanks!
I edited "@baseboard-industrialio.c@" and set the USB mode as peripheral. Somehow, our custom board ne...

Woops sorry I was looking at the 2.6 kernel sources. In the 3.2 branch Peripheral mode can be configured in the baseboard. - OÇ 08:47 AM Software Development: RE: Linux USB Gadget is not working on custom board

By default, CONFIG_USB_MUSB_OTG is selected which puts the kernel in OTG mode. In this mode, if USB*_ID is pulled low then the device enters host mode and if its left floating then its in Peripheral mod... - OÇ 01:27 PM Software Development: RE: Linux USB Gadget is not working on custom board

Yes, I see those lines even when not connected to the host.
I did a @dmesg@ in the Critical Link board, but those lines don't appear there (when not connected).

In our tests, the device acts as the peripheral and the computer as the host.

If you do a dmesg (before and after plugging in a USB device), do you see anything related to USB?

We've been working on a MityDsp-L138F SoM and so far managed to use USB GadgetFS feature of the Linux kernel to send and receive bulk data through USB 2.0.
We also have a custom-manufactured board based on MityDsp. To adapt the...

We've been working on a MityDsp-L138F. The ARM and DSP cores run Linux and SYS/BIOS, respectively. We're using SysLink for inter-processor communication. Specifically, we send Notify events between the cores. Up to this point, eve...

Changing that to @ttyS2@ solved that issue.
Sorry, I wasn't expecting such a simple solution. - Hi,
We've been working on a MityDsp-L138F board, and I can boot to Linux with NFS, with the following environment variables:
