Partial boot z9X #30

Closed MEH661905 closed 11 months ago

MEH661905 commented 11 months ago

Hi, I found your guide a helpful start with a z9x I can't get to boot. Can't flash either, but I'm stuck at step 2. I can read the UART but can't get to enter commands. I get the start of the initialisation, but then stops after this: process_dte_fw_certificate: 0x0 get_dte_bootcode_rtk = 0x00000000 copy_img_from_emmc(00000000, 00000d00, 00180000, 00030000) process_dte_bootcode_rtk: 0x0 jump to BL31: 0x80001000

There is no response to me holding/pressing ESC. I've forced Echo on to make sure I'm sending Ctrl[ Not sure where to go next? Any ideas? I'm reasonably technical (science background) but definitely not a programmer/developer.

Maybe bootloader broken. I don't know how to repare bootloader on RTD1619. I have only RTD1296 bootloader.

If you know how to flash whole emmc flash, you can use this image https://mega.nz/file/vbo3GahS#XtGkryVTk-fho4_gN9FnefjcyiOzYsMQ--9euGT2DTw , unzip it and write it to emmc on 20744 block (512 bytes per block)

Thanks, I'll give it a try at the weekend.
