esp8266 keeps rebooting #436

Open tclarke opened 5 years ago

tclarke commented 5 years ago

I'm having trouble getting esp-link working on a reference esp8266 board. I've tried v3.2.47 alpha and v3.0.14 with the same results.

esptool.py v2.5.1 Found 2 serial ports Serial port /dev/cu.usbserial-AK06VCCU Connecting.... Detecting chip type... ESP8266 Chip is ESP8266EX Features: WiFi MAC: 5c:cf:7f:b5:d6:82 Uploading stub... Running stub... Stub running... Manufacturer: e0 Device: 4014 Detected flash size: 1MB

I flash with:

Leaving... Hard resetting via RTS pin...

I shift GPIO0 to high and monitor with a serial terminal. I'll get the following and a reboot repeating.

try DIO mode for flashing

tclarke commented 5 years ago

Just tried DIO at 80mhz and 40mhz. It's rebooting more quickly now:

You can try also flash with blank.bin to reset all flash to 0, sometimes there are some garbage in flash. Try to use boot 1.6 instead of 1.7
