Flashing tool doesn't work.

[asperks]

I have AI-Thinker ESP-12 chips (seven chips, two different suppliers), and I can't get any of them to flash and word with the espressif firmware. It flashes, it says that it is successful, but I get either fatal errors when connecting after the flash, or I get constant resets.

I've attached a screen capture of the flashing setup that I've used, using the espressif ESP Flashing Tool and used the address offsets in the documentation.

When I use coolterm to attempt to connect to the port, it just crashes me out. When I use AppStack ESP Config tool, I can see the terminal, but I'm getting constant fatal errors. The error message is just a repeating of this.

Fatal exception (0):
epc1=0x402415a4, epc2=0x00000000, epc3=0x00000000, excvaddr=0x00000000, depc=0x00000000

Can someone tell em what I'm doing wrong? Is there some part that I'm missing in the flashing utility?

Hi，

You should compile and download user1.bin, not user2.bin.

boot_v1.4(b1).bin 0x00000
user1.1024.new.2.bin 0x01000
blank.bin 0x7e000
