chip_detect_error on ESP32-P4 #679
Description
When using espflash 3.1.1 on the P4 dev board, it fails to detect the chip:
$ espflash board-info
[2024-09-12T15:32:39Z INFO ] Serial port: '/dev/ttyUSB0'
[2024-09-12T15:32:39Z INFO ] Connecting...
[2024-09-12T15:32:39Z INFO ] Using flash stub
Error: espflash::chip_detect_error
× Unrecognized magic value: 0xffffffff
help: Supported chips are: esp32, esp32c2, esp32c3, esp32c6, esp32h2, esp32p4, esp32s2, esp32s3
If your chip is supported, try hard-resetting the device and try again
Hard resetting results in the same error.
Flashing a C build with EPS-IDF works fine over the same ttyUSB0. Not sure which details can be provided that would help here.
