Hello,
I have a i.mx6q sabre SD board and I want to try it with genode and TrustZone
feature. I found there's a related issue:
https://sourceforge.net/p/genode/mailman/genode-main/thread/5535FB27.1090605%40iritech.com/#msg33940450,
I tried it with Genode as secure world
(https://github.com/iitmadras/genode/tree/hw_sabrelite_tz_support) and
met the same problem that it stuck at :
Starting Kernel ....
And the solution mentioned it was about the UART configuration difference with
sabre Lite and sabre SD board. However, I am little confused with it.
First, the sabre Lite and sabre SD board are both equiped with 4 i.MX6
processor, so I think the UART address are same which can be found in "i.MX
6Dual/6Quad Applications
Processor Reference Manual", so I can not understand where is the UART
configration difference. Also, I have tried to modify the UART_1_MMIO_BASE in
[1] to all the UART address
in "i.MX 6Dual/6Quad Applications Processor Reference Manual", but the problem
still exist.
Second, when I create the build dir with: ./tool/creat_builddir hw_sabrelite
and try it with run/printf, it can successfully print the message. But when I
create the build dir with:
./too/creat_builddir hw_sabrelite_tz and try it with run/printf, it stuck at
"starting kernel ..." . In other words , I cannot get the print message
successfully with TrustZone.
Please give me advice to fix this problem. By the way, I want to know if
there's any newer version that I can try genode with TrustZone on i.mx6.
Thanks a lot.
