TTGO CAN-485 : A fatal error occurred: Failed to write to target RAM (result was 01070000: Operation timed out) Failed uploading: uploading error: exit status 2
Product : TTGO CAN-485
Platform: Arduino 2.0.4 / Modbus Maste 2.0.1
After successful compilation, Arduino is unable to flash the esp32 :
Sketch uses 968985 bytes (73%) of program storage space. Maximum is 1310720 bytes. Global variables use 51432 bytes (15%) of dynamic memory, leaving 276248 bytes for local variables. Maximum is 327680 bytes. esptool.py v4.5.1 Serial port /dev/cu.usbmodem54F40127791 Connecting.... Chip is ESP32-D0WDQ6-V3 (revision v3.0) Features: WiFi, BT, Dual Core, 240MHz, VRef calibration in efuse, Coding Scheme None Crystal is 40MHz MAC: 4c:eb:d6:43:58:80 Uploading stub... A fatal error occurred: Failed to write to target RAM (result was 01070000: Operation timed out) Failed uploading: uploading error: exit status 2
Steps to Reproduce:
- Click compile and upload
The new firmware should be flashed into the esp32
The firmware is unchanged and then useless.
- I tried two different boards, I got the same result
- I tried with two different USB cables, I got the same result
- I tried holding reset and bot, bot only, reset only, bot hold and quick push on reset, I got the same result
- Reboot board and computer
Do you have some ideas for me ?
I didn't found on the official github repo the role of BOT button.
