ESP32 Lora 1-CH Gateway (WRL-15006) upload problems

Wireless & IoT LoRa (Long Range)

Uploading code to this card now fails unconditionally. It has been working, I have loaded the Gateway code using both the Arduio as well as PlatformIO. But the uploading has been erratic. Now it is impossible. The card seems to run into a tight loop ignoring enything else while printing:

rst:0x10 (RTCWDT_RTC_RESET),boot:0x33 (SPI_FAST_FLASH_BOOT)

flash read err, 1000

ets_main.c 371

I have tried to clear the flash using esptool but the same thing happens:

esptool.py -p com8 erase_flash

esptool.py v3.0

Serial port com8

Connecting…

Detecting chip type… ESP32

Chip is ESP32-D0WDQ6 (revision 1)

Features: WiFi, BT, Dual Core, 240MHz, VRef calibration in efuse, Coding Scheme None

Crystal is 40MHz

MAC: 4c:11:ae:89:9d:2c

Uploading stub…

Running stub…

Stub running…

Erasing flash (this may take a while)…

A fatal error occurred: Timed out waiting for packet content

But also this fails unconditionally.

Are there anything I could do to get this card working again?

Thanks for reaching out to us on this.

Those are the correct steps for troubleshooting; perhaps also attempt:

Flashing from a different host computer (or OS)

Switch to a different cable to ensure it isn’t the issue; double-check the board for loose connections/parts

Try a different version of ESPTool?

Electronic parts also simply wear out from use; it may have reached its end-of-life (MANY factors determine the lifetime of a product…if it was ~30 days ago or less that you purchased it, we can get you squared away with a replacement)

Hope this helps, and happy sparking!
