09:57 AM Software Development: RE: Changing UART1 to UART2 in Linux Kernel
Just noticed I left the @bootargs@ as @ttyS1@.
Changing that to @ttyS2@ solved that issue.
Sorry, I wasn't expecting such a simple solution.

05:32 AM Software Development: Changing UART1 to UART2 in Linux Kernel
Hi,
We've been working on a MityDsp-L138F board, and I can boot to Linux with NFS, with the following environment variables:

VP 11:56 AM Software Development: Low frequency input (5 Hz to 20KHz processing) for mitydspl138F
Hi,
I have a custom board with
1) MityDspl-138F module (with FPGA)
2) No Ethernet port
3) UART,USB,SD CARD interface
4) We are using ADC5560 and DAC5672, reference is taken from Analog Expansion Board.
ADC and DAC both operat...

It doesn't look like we ever created that guide. I'd recommend looking at the provided source files as examples.

You'd want to extract the MDK filesystem, update the files and then generate the jffs2 image file. NOTE: We also generate a new tarball which we can archive o...

10:52 AM Software Development: Interrupts Between Linux and DSP without BIOS
Hi,
I've been working on a MityDsp-L138F with Linux Ångström.
I'm able to use the 128-KB shared RAM for inter-processor communication between the two cores, with ARM running Linux and DSP running baremetal. I want to send interrupt...

TR 10:06 PM FPGA Development: RE: Alternate GPIO Control
Greq, good point WRT the inouts... thanks for bringing it up. In our case they were going to be dedicated outputs. Either way it's great that CL supplies those cores, no doubt they will be utilized. Regs, Tom

GG 09:39 PM FPGA Development: RE: Alternate GPIO Control
Hi Tom,
One concern I have regarding your proposed approach would be the case of your GPIOs needing to be run-time configured as inputs or outputs. Configuring your FPGA passthrough ports to be inouts may be sufficient, but you may a...

TR 07:23 PM FPGA Development: Alternate GPIO Control
Hi,
Direct GPIO control from the L138 is pretty nice to have. In our current task we need a number of GPIOs, more then what is available on the expansion connections when considering the other L138 functions we are using. The ability...

JC 02:28 PM Software Development: RE: How to activate splash screen
Note you can load the fpga from u-boot. https://support.criticallink.com/redmine/projects/arm9-platforms/wiki/Programming_the_FPGA#Using-u-Boot-to-load-the-FPGA Jonathan Cormier
JC 02:27 PM Software Development: RE: How to activate splash screen
The LCD requires the fpga to be programmed if your using a L138 with fpga. Perhaps that's whats holding the LCD off until end of boot. Jonathan Cormier
AH 06:28 AM Software Development: RE: How to activate splash screen
I found out that the psplash service in /lib/systemd/system is not available. so i make a psplash.service script Andri Haryono
