android_Q10.0.0_2.0.0 SPL cannot load ATF startup

[aber]

If the DEBUG serial port is UART2 according to your own platform, SPL cannot load ATF and stops at the following log。the same problem occurs with EVK development boards.Attached is the modified patch。

Help to analyze what is the problem。Tks!

Read 3.3.2 Generating and fusing the eMMC RPMB key in i.MX_Android_Security_User's_Guide.pdf

Seems like you missed rpmb key

There is no problem with uart1. The main reason is that the M4 core uses UART2, and we are still looking for a way。Tks!

Hi Aber

one can try to debug ATF with "#define DEBUG_CONSOLE" in

platform_def.h\include\imx8mq\imx\plat - imx-atf - i.MX ARM Trusted firmware 

or try with jtag using app note

Normal and Secure Debug for i.MX8/8X Family of Applications Processors

#define DEBUG_CONSOLE 1

Log will print the following information。

may be recommended to rebuild all image from scratch.

Just empty and recompile the same problem。

[igorpadykov]

uart2 is used by m4 in SDK_EVK-MIMX8MQ so one can try

to assign properly rdc permissions to a53 in atf bl31_imx_rdc_setup(),

that is set UART2 RDC_PDAP105  read/write permissions for Master 0  A53

imx8mq_bl31_setup.c\imx8mq\imx\plat - imx-atf - i.MX ARM Trusted firmware 

RDC is described in sect.3.2 Resource Domain Controller (RDC)

i.MX 8M Dual/8M QuadLite/8M Quad Applications Processors Reference Manual

Hi Igor,

We have the same issue.  Could you provide exact codes to add/modify under the imx8mq_bl31_setup.c?
There are a lot to digest in the section 3.2 Resource Domain Controller (RDC) under the Reference Manual.  

Thanks,

BL

Is there any way to solve it. There is no such problem on Android 9。
