Building for a custom board #89

Closed metanav closed 10 months ago

metanav commented 10 months ago

I am trying to build the launcher+prboom-go firmware for the target Nano ESP32 (ESP32-S3, 8MB PSRAM, 16 MB Flash) and an Adafruit ILI9341 LCD shield. I used the esplay-s3 target and have modified pins in the file components/retro-go/targets/esplay-s3/config.h.

$ ./rg_tool.py --target esplay-s3 build-img prboom-go
$ esptool.py --chip esp32s3 write_flash   --flash_size detect   0x00  retro-go_1.39-pre-dirty_esplay-s3.img

Here is the log that was displayed during the flashing process.

The board continues to reboot despite successful firmware flashing. The serial console displays an error message.

Did I miss any configuration or steps to build for my DIY custom setup?

It is fixed now. I had to change the bootloader.bin address from 0x1000 to 0x00 for ESP32S3 in the image build script.
