SYS/BIOS
Added by Martin Hantke over 6 years ago
Hello Forum,
i have a question related to usage of TI SYS/Bios on MiTyDSP without FPGA.
i successsfull flashed my app.out file to the external SPI via u-boot.
I see GPIO working also UART.
If i call BIOSStart nothing happens further.
I only have one task with Blinking LED.
If i run my appliction in debug Mode with your .gel-File all works fine.
I believe i missed some Initialisation?
Especially which Power Domain have to be enabled?
Many Thanks for any answers
Regards Martin

Finally i could solve this issue by adding the following code :
asm(" mrc p15, #0, r0, c1, c0, #0\n\t"
" orr r0, r0, #0x00002000\n\t"
" mcr p15, #0, r0, c1, c0, #0\n\t");
before calling BIOS_start function.
Thanks everyone.
thanks too Ahmed Shaaban
regards
Martin
