My read attempt (ESP32) aborts around 30-32% every time using chrome.
Using python tool I get “A fatal error occurred: Corrupt data, expected 0x1000 bytes but received 0xeff bytes”.
Has anyone an idea?
Thanks.
Check your wiring and your USB UART. You may try to lower the baudrate with the esptool, when the connection is unstable.
i had the same issue on a Mac. Switched to Windows and it worked for me
On my Mac I also got the Corrupt data error message. Using the default baudrate of esptool did work better for me:
esptool.py read_flash 0x0 0x800000 tb.esp32.bin
See Basic Options - ESP32 - — esptool.py latest documentation for more options. The default baudrate should be 115200bps.
