Description v9sd 2021-07-12 14:45:42 UTC

Hello!
I have a problem with op-tee start on imx8mm_evk (https://www.nxp.com/design/development-boards/i-mx-evaluation-and-development-boards/evaluation-kit-for-the-i-mx-8m-mini-applications-processor:8MMINILPD4-EVK).

My .config file is attached.


I write output/images/sdcard.img on sdcadr, connect terminal emultaion with serial port and start imx8.

After below output imx8mm_evk is output nothing.

Problem arises after jump execution on op-tee entry point address (0xbe000000)


After reaching the above address breakpoint, we have content in memory: 

(gdb) x/10i $pc
=> [34m0xbe000000[m <[33m_start[m>:     .inst   0x00150000 ; undefined
   [34m0xbe000004[m <[33m_start[m+4>:   .inst   0x00000000 ; undefined

   [34m0xbe00000c[m <[33m_start[m+12>:  .inst   0x00000000 ; undefined
   [34m0xbe000010[m <[33m_start[m+16>:  .inst   0x00000000 ; undefined
   [34m0xbe000014[m <[33m_start[m+20>:  .inst   0x00000000 ; undefined
   [34m0xbe000018[m <[33m_start[m+24>:  .inst   0x00000000 ; undefined
   [34m0xbe00001c[m <[33m_start[m+28>:  .inst   0x00000000 ; undefined
   [34m0xbe000020[m <[33m_start[m+32>:  .inst   0x00000000 ; undefined
   [34m0xbe000024[m <[33m_start[m+36>:  .inst   0x00400000 ; undefined

As we look, it is not valid instructions opcode.

After continue execution, imx8 freezes.

Guess that the op-tee was not load in memory in uboot-spl.
