I'm trying to get started with the 3530 EVM board from Mistral and the latest PSP from TI.
I downloaded and unpacked the AM32x-OMAP35x-PSP-SDK-03.00.01.06.tgz file from the TI website.
I then set up U-Boot to tftp the kernel provided at images/kernel/omap3530/uImage and boot it.
I also downloaded and unpacked the nfs_dvsdk_03_01_00_06.tar.gz file, and setup U-Boot to pass the appropriate bootargs to mount it over NFS.
When I boot up, I get the errors shown below - here are my questions:
1) Do I need to worry about the 'display already enabled' error? Later when it tries to start the demo, I don't see anything on the display...
2) Why would the Graphics pipeline underflow and disable itself during boot? Will this cause problems later when an App tries to use it?
3) Why doesn't the root filesystem have a valid modules directory for the kernel (kernel is 2.6.32, fs has 2.6.29 modules)? I don't think I need any modules (all required functionality is compiled into the kernel?), but the 2.6.29 sub-tree does contain a few modules. I can eliminate the error by simply creating an empty 2.6.32 directory, but isn't this an issue that should be fixed in the provided root fs?
4) Am I missing some key factor in getting the board to boot up correctly? My bootargs are:
Kernel command line: console=ttyS0,115200 noinitrd root=/dev/nfs rw ip=192.168.16.6 nfsroot=/home/rball/roots/psp3.0729 mem=99M ip=192.168.16.235:192.168.16.6:192.168.16.1:255.255.255.0::eth0:on omapfb.rotate=1 omapfb.rotate_type=1
Thanks in advance for any help.
Rick
