Title: ESP32-EVB / flash read err, 1000
Post by: dile on April 05, 2018, 06:07:43 PM
Hello,
I got an ESP32-EVB and plugged it on the usb cable. I continuously get the following messages:

....
rst:0x10 (RTCWDT_RTC_RESET),boot:0xb (HSPI_FLASH_BOOT)
flash read err, 1000
Falling back to built-in command interpreter.
OK

Falling back to built-in command interpreter.
OK

Is the board broken, or am I missing somehting?

Thank you

The CH340 allows max. baud rate to be 115200, so make sure you select that (run 'make menuconfig') and then 'make flash'.

This is normal message out-of-the-box. Nothing is executing since there is no user program loaded. Upload some user software and test again. If the problem persists try with another USB port since under power might also cause this message.
