- Hi Craig,
Other than trying to re-seat the module and the serial port cables in their respective connectors, I don't have any other suggestions. If the board is not presenting the "BOOTME" description, then there must be hardware fa... - CM 11:50 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Eval Board will not boot

Can you please monitor the console (115200 baud, no flow control) and, while holding the boot button down, press the reset button? You should see "BOOTME" appear on the screen. Can you please confirm?
Also, can you plea... - Purchased 3 kits 80-000268RI-1 with SoM L138-FI-225-RC. One kit does not boot when power is applied. Green LED does light to indicate power. Monitoring serial port in hyperterminal same as we did for the other two kits that boot fine. Fo...

Is there anywhere in the wiki that explains how to set up the dsplink driver on the ARM? When I run ./HelloWorld HelloWorldDSP.out it fails to open the driver, which should be located in /dev/dsplink according to the error I ge... - GG 09:44 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: HelloWorldDSP.out syntax error

With the latest MDK there is no need to rebuild DSPLink. I've updated the DSP Hello World wiki page to outline where the libraries are located that you need to link against in order to build the Hello World example for the AR... - ML 09:13 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: HelloWorldDSP.out syntax error

- Hi Zoltan -
You are correct. Thank you for pointing this out!
This fix will go into the next build of boards. I apologize for any inconvenience.
Thanks,
Tom - Hi,
Sorry I post my problem here, but there is no forum for the industrial board.
We had issues with some USB devices using the mini-B USB connector, and it seems the pin-out is wrong, and the ID (pin4) and GND (pin5) is swapped.

I'm not seeing this same behavior on my system. Can you give me more details? It seems you're running with the latest MDK, but did you change anything else on your board? Namely, what dsplinkk.ko module are you loading (the o... - MC 07:21 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: HelloWorldARM DSPLINK example causes Assertion failed

- Hi Marc,
With the latest MDK you should not actually need to rebuild DSPLink (I'm updating the DSP Hello World wiki to reflect this now).

I'm good with my version, and I'm not in a hurry to upgrade my kernel.
Btw I'm using mitydspl138 with the industrial base board (revD) (if it matters)
Thanks again for your help!
Zoltan - MW 12:28 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: mtdblock kernel crash

We've confirmed the SPI issue and are working on it. There were a couple of patches to the (linus) mainline regarding the SPI drivers that may be impacting your use case (there was a problem with 65535 or more byte accesse... - ZC 12:18 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: mtdblock kernel crash

Here is some extra information:

- MW 08:34 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: mtdblock kernel crash

Do you have anything running on the DSP while this is going on? Or is it still in IDLE / RESET?
- MW 08:32 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: mtdblock kernel crash
- 1. OK.
2. Fair enough, didn't catch that originally.
3. Sure, I'll get you something tomorrow.
Couple more questions, if you don't mind....
Do you happen to know what git revision you were using when life was good? Do you ha... - ZC 07:20 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: mtdblock kernel crash

1. Toolchain:

2. Root FS is in ram (NOT mtdblock0):

- Can you try the same command without mounting /dev/mtdblock0 as the rootfs? (e.g., stay in your ram initrd filesystem)
It's a little weird that you're trolling around /dev/mtdblock0 NAND if you have it mounted as your root filesystem.... - ZC 06:34 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: mtdblock kernel crash
- Mike,
It was a clean copy. I've made changes only to make it buildable from Windows (Cygwin). But those changes were made for my previous kernel revision.
Btw "hexdump -C -n 64 /dev/mtdblock1" works fine.
Zoltan - MW 06:19 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: mtdblock kernel crash
- Hi Zoltan,
We'll need to try to reproduce this here. It may take a day to get to it.
When you rebuilt, did you do a make clean first? Or did you pull a clean copy of the kernel down?

I've got the latest linux kernel image, defconfig'd it, enabled SPI flashes, and nuilt the kernel.

- Mark,
A new BSP has been posted. The serial port driver has been changed so that with a -M option, it will not enable the modem state interrupt. For some reason, on the newer revision board/module, there are a lot of these interrupts ... - ML 03:08 PM ARM9 Based QNX Platforms Software Development: RE: 1st time boot up
- Great, thanks.
FWIW I've verified USB and Ethernet works fine. I can comment out all the ports and run from the serial port as setup by u-boot, and I can telnet in too.

It has been a little while and I wanted you to know that we have reproduced this problem and are working on a fix.

I do want to use UART0, I was just trying that to see if it was the problem.

Are both uart0 and uart1 available?
Is u-boot using uart0?
Did you change the pinmux configuration to turn on uart0?

Most of the files you need are in the latest tarball release. I've sent you the remaining files, which will be added as a part of our next release.
Let us know if you have any further issues.

I am also looking for these files...
Could you email me them too?
