Hi,

I have followed the steps provided in http://www.slideshare.net/linaroorg/lcu14-302-how-to-port-optee-to-another-p...

I am able to progress further after defining TEE_SCATTER_START, STACK_TMP_SIZE, STACK_THREAD_SIZE in platform_config.h as suggested in http://www.slideshare.net/linaroorg/lcu14-302-how-to-port-optee-to-another-p...

I am able to compile and generate tee.elf using arm-none-eabi- toolchain.

While porting on to ARMv7 board, the control is halted while executing the "static bool is_valid_conf_and_notnull_size(vaddr_t b, size_t bl, vaddr_t a, size_t al) function" in tee_misc.c at the below point.

/* invalid config return false */ if ((b - 1 + bl < b) || (a - 1 + al < a))

Please suggest me on how to resolve this and proceed further.

Regards, Ajith

Hi,

I am trying to port Optee-os on a new platform which contains ARM cortex A5.

Updated DRAM_BASE_ADDR, DRAM0_SIZE, CFG_TEE_RAM_START, CFG_TA_RAM_START, CFG_PUB_RAM_START accordingly.

compiled and built tee.elf for the new platform.

But when I tried to port tee.elf on the new platform, it is failing while executing "pbuf_intersects" in core_init_mmu_map in core_mmu.c

Please suggest me how to proceed further. Please let me know if I missed anything.

Regards, Ajith
