Module

ESP32-C3-WROOM-02

Issue

Use esptool.py to flash ESP32-C3, it works after the module is reseted.
Use https://espressif.github.io/esptool-js/ to flash same images with the address the order:(0x0, 0x8000, 0xe000, 0x10000), it works after the module is reseted.

the error is "esp_image: image at 0x10000 has invalid magic byte"

…app image flashed at first espressif#48

LeoYan · 2022-11-03T08:29:05Z

The reason:

if fileArray[i].data.length % 4 == 0, there will be extra 4 bytes, so overlap with the following image
image = fileArray[i].data + '\xff\xff\xff\xff'.substring(0, 4 - fileArray[i].data.length % 4);

btw:
2. the address of C3 bootloader is 0x0 rather then 0x1000
