ESP32 CO-PROCESSOR PROBLEM

by johncblacker on Wed Apr 21, 2021 12:14 pm

I'm trying to use a ESP32 DEVKIT board as a co-processor but am not getting past the first stage of flashing the firmware onto the board. I downloaded the NINA_W102-1.3.0.bin firmware and changed the name to NINA_W102.bin. I'm using esptool.py -p com21 -b 115200 write_flash 0 NINA_W102.bin
and get these results:
esptool.py v2.5.1
Serial port com21
Connecting......
Detecting chip type... ESP32
Chip is ESP32D0WDQ6 (revision 1)
Features: WiFi, BT, Dual Core, 240MHz, VRef calibration in efuse
MAC: 9c:9c:1f:c7:af:28
Uploading stub...
Running stub...
Stub running...
Configuring flash size...
Auto-detected Flash size: 4MB
Compressed 1154048 bytes to 622216...
Wrote 1154048 bytes (622216 compressed) at 0x00000000 in 55.6 seconds (effective 166.1 kbit/s)...
Hash of data verified.

Leaving...
Hard resetting via RTS pin...
Next I try to use tera term to connect to the board, but when hitting the "en" button (I think that's the reset?) I get the following error:
ets Jun 8 2016 00:22:57

rst:0x1 (POWERON_RESET),boot:0x17 (SPI_FAST_FLASH_BOOT)

load:0x40078000,len:9400
load:0x40080400,len:5696
entry 0x40080678
As you can see, I get a read error 1000. I don't know how to proceed or what, if anything, I'm doing wrong and need some guidance.
TIA
