add v4l2 driver in 8148 EVM

Hi,

I think you forgot to load the binary. Following are the steps to be followed to load binary.

Shah,

Thanks for your help

My steps were:

Will you help me?

Hi,

It seems you have 512MB board and you are trying to load 1G binary. Please confirm that you have 1GB board and not 512MB board. If you have 512MB board u-boot will also require change. which PSP release are you using?

Regards,

Hardik Shah

Shah,

Thanks for the very quick response.

I think i have 512MB board.I change my u-boot argument,but result is same!

The bootargs are:

bootfile=uImage-dm814x-evm.bin
bootargs=console=ttyO0,115200n8 rootwait rw mem=256M earlyprintk notifyk.vpssm3_
sva=0x8DB00000 vram=50M ti814xfb.vram=0:16M,1:16M,2:6M root=/dev/nfs nfsroot=192
.168.2.76:/root/targetfs ip=192.168.2.79

PSP:linux-2.6.37-psp04.01.00.06.patch2

Can you tell me how to do it? Could you provide the bootargs and all steps to load M3 firware and modules?

Thanks,

zhan

Hi,

I think you have to change u-boot code also for 512MB board. You can refer to u-boot userGuide for same. Further you need to load 512MB .xem3 which is packaged with PSP.

Hardik Shah

Zhan,

the firmware inside PSP release is different with the one in EZSDK, they have different memory map.

for the EZSDK firmware: please read below link:

http://processors.wiki.ti.com/index.php/EZSDK_Memory_Map#Changing_Memory_Map_For_512MB_Board

for PSP firmware, please read below link:

Hi Hardik,

If I want to work on v4l2 capture, do I still have to use 512MB .xem3 or still use dm814x_hdvpss_v4l2.xem3?

Please confirm this.

Thanks,

Jun
