I was able to enable early debug UART in U-Boot and I will try to find what is happening, once I get some free cycles.
Ok, this was relatively easy to find :-)
New versions of EEPROM firmware change “kernel”/U-Boot load address from 0x80000 to 0x200000. And because on RPi’s CONFIG_TEXT_BASE is hardcoded to 0x80000 code run through the fields.
Hopefully simple patch like bellow make it work fine in older and newer EEPROM firmware versions.
Thanks for this tiny but important fix on your patchset. In fact, I was able to verify that now with your latest v5 patchset for the initial rpi5 support even newer/latest rpi-eeprom versions work as expected and u-boot is chain loaded by the rpi boot loader.
thank you for testing. Could you please give your Tested-by to v5 or at least parts of them?
So thanks again for that fix and I am looking forward to seeing your patchset integrated and hopefully also maintained in future so that USB boot and GPIO support will be added in the near future.
