Build ARM Trusted Firmware from source + use JTAG on RK3399

tuan2195 · Posted at 9/19/2017 02:31:42

I have two question:

1. Where is the source code so that I can build ARM Trusted Frimware (bl31.bin) from source? I need to modify ATF in order to run some code at EL3.

I have tried using https://github.com/ARM-software/arm-trusted-firmware but there is no instruction on how to build it for this particular board. Are there any specific build options?

2. How do I use JTAG on RK3399? There seems to be no guide on this. Thanks.

Hi Tuan, did you ever figure this out in the end?

Rockchip seems to be maintaining a repo and it is quite active. Link is given below.

https://github.com/rockchip-linux/arm-trusted-firmware

I'm not fully aware between the differences between this and the one maintained by ARM. Just FYI, you can explore further.

Thanks,
San
