Ezsdk Arago base filesystem startup problem

Pierre-Olivier Belzile

Hi, with the objective of building my own filesystem, I installed the "arago-base-tisdk-image-dm816x-evm.tar.gz" and tried to boot it. It finally boots but after a rather long delay and many error messages related to the vpss/sii9022a drivers modules (see attached log).

I wonder if the boot args are wrong. Here is what I currently use:

console=ttyO2,115200n8 rootwait rw mem=256M earlyprintk notifyk.vpssm3_sva=0xBF900000 vram=50M ti816xfb.vram=0:16M,1:16M,2:6M root=/dev/nfs nfsroot=192.168.0.100:/home/user/targetfs ip=dhcp

Any idea what the problem is ? Does the VPSS tries to start but fail because the m3 firmware is not loaded ? How can I avoid that ?

Regards,

Pierre-Olivier

    This is a known issue of EZSDK. The I2C used to control SII9022a is controlled via M3 Firmware. So when trying to access SII9022a from Linux(A8), I2c shows timeout error. Please do not load sii9022a module for know. SDK is already working on this.

    Hi Yihe, I'm still experiencing problems with the arago base filesystem image provided with the latest SDK (5.03.01.15). The VPSS module apears to be in trouble, see the atached log. What should I do in order to trouble shoot the problem ?

    Pierre-Olivier,

    I've seen this type of behaviour as well. In my case it was because the arago file system had some pre-installed *.ko files for vpss and sil9022 that did not match the kernel.

    I solved it by removing the following files from the files system.

    /lib/modules/2.6.37/kernel/drivers/video/ti81xx/vpss/vpss.ko and /sii9022a.ko

    Thanks Iain, it worked for me to. Now all I have to do is to load the right module...

    What modules did you end up using for your design?
