Re: MicroPython on ESP32 with SPIRAM support

I have two ESP32 boards: M5STACK with 4M SPIRAM and ESP-WROOM-32. Both of them can flash the standard Firmware successfully from http://micropython.org/download and work well. But both of them failed to flash the firmware with SPIRAM firmware from https://github.com/loboris/MicroPython_ ... /firmwares. ESPFlashDownloadTool and esptool.py are used and neither of them work. Is there some difference to flash these two version of firmwares? Thank you.

Have you followed this guide? Installation instructions are different for the Loboris build.

Thank you for your reply. The problem has been solved. It's my mistake. I ignored the bootloader.bin and/or partitions_mpy.bin, which are not required for the standard version.
