How to run sys/bios example after uboot on TCI6636K2H ev board ?
I would like to run simple example after uboot without gel file.
- I don't want to use default gel file ( xtcievmk2x_arm.gel )
- Import hello_TCI6638K2K_CortexA from ccs resource browser and build & make bin file
- mkimage -A arm -T kernel -C none -a 0x80000000 -e 0x800050ec -d hello_TCI6638K2K_CortexA.bin hello_TCI6638K2K_CortexA _for_uboot.bin
- Power on TCI6636K2H ev board.
- Download hello_TCI6638K2K_CortexA _for_uboot.bin @0x80000000
- bootm 0x80000000
but It is not working
When I did same test with Trace 32 to monitor detailed information, I found data abort between _c_int00 and main().
The aborted line was auto generated code by sys/bios.
vmsr fpexc, r0
At that time, Arm Core Regsiter NSACR was 0x0 and arm was nosec mode.
Please let me know what is correct way to run sys/bios example after uboot.
