firmware_loader error on DM814X custom board

Hello,

What is the software release that you are using here?

Could you try with the this bootargs:

setenv bootargs 'console=ttyO0,115200n8 rootwait root=/dev/mmcblk0p2 rw mem=256M earlyprintk notifyk.vpssm3_sva=0xBF900000 vram=50M vmalloc=500M ti814xfb.vram=0:16M,1:16M,2:6M ip=off noinitrd'

Also could you check the loaded .ko file. Could you provide more details about what change are made? Did you make some memory map changes? Could you rebuild syslink module and load it?

Let me know the result.

BR

Margarita

Hi Margarita,

1. We are currently using ezsdk 5.05.02.

2. We have tried the bootargs as given by you. We are getting the below dump

3. We dint do any memory changes, We have followed the EZSDK porting guide from the below link.

http://processors.wiki.ti.com/index.php/EZSDK_Memory_Map#Modifying_Memory_Map

We have used the below bootargs,

setenv bootargs 'console=ttyO0,115200n8 rootwait root=/dev/mmcblk0p2 rw rootfstype=ext3 mem=364M@0x80000000 vmalloc=500M earlyprintk notifyk.vpssm3_sva=0xBF900000 vram=50M ip=off noinitrd'

With these args, we are able to load the cmemk module, and we are getting the similar error as posted in our earlier post.

Kindly let me know what changes in syslink will help us get out of this issue.

Hi Margarita,

when we are specifying 2 blocks of memory for the kernel in the boot parameters

setenv bootargs 'console=ttyO0,115200n8 rootwait root=/dev/mmcblk0p2 rw rootfstype=ext3 mem=364M@0x80000000 mem=320M@0x9FC00000 vmalloc=500M earlyprintk notifyk.vpssm3_sva=0xBF900000 vram=20M'

then if we are trying to load cmemk.ko then it is giving the following error.

root@dm814x-evm:~# insmod /media/mmcblk0p2/lib/modules/2.6.37/kernel/drivers/dsp

Here kernel is taking continuous memory so we are not able to load the cmemk module.

kindly help us in resolving this issue.

Hello,

I did not understand how you modify the memory map is it for 512MB, 1G and etc board?

Hi Margarita,

We have configured for 1GB only.

Hi Kiran,

on our custom board while trying to load the vpss module, iam getting following error

Why are you trying to load the vpss module manually? I mean we have a script which is loading the vpss module and firmware automatically during the boot process. Have a look in the {ROOTFS}/etc/init.d/load-hd-firmware.sh script.

Are you booting your custom board from SD card? If yes, please use the below approach to make an EZSDK 5.05.02.00 bootable SD card:

Hi Kiran,

Reduce your Linux memory to 176MB,

setenv bootargs 'console=ttyO0,115200n8 rootwait root=/dev/mmcblk0p2 rw mem=176M earlyprintk notifyk.vpssm3_sva=0xBF900000 vram=50M vmalloc=500M ti814xfb.vram=0:16M,1:16M,2:6M ip=off noinitrd'

You should be able to insert cmemk
