I have an ESP-01 that I've been developing on (for the Frankenstein firmware).

Since last night, the blue LED is constantly on, and it's started spewing data out on the serial port.

I can enter the reflash-mode, and it looks like reflashing seems successful, but after reset the blue light glows constantly on, and it keeps spewing binary data out on the serial port. The binary data looks like its a block of 165 bytes repeated.

Has anyone had an issue like this and resolved it?

I had the same problem with esp-01 and esp-03. it seems power issue. esp-01 consume 33-55ma in the flash mode soo it run on flash mode and it cant run normal mode maybe. but normal working up to 300ma. you can try read data for bootloop(try baudrate 74880)

I have the same problem, after flashing not the latest FW from Nekromant, then this happend bootloop. So I flashed Lua FW and its ok now. Try to flash another FW. For my it helped.

Thanks for the tips everyone!

I've tried them all, but unfortunately it still seems to be in a boot loop.

I guess I'll have to buy a new one. Mainly bugs me to have to wait a couple of weeks to keep working on this.
