Hello, When I try to connect my ESP01 board it works fine, I send AT and I get an OK.
Problem is happening when I update the firmware. Please see screenshots to know how I am doing it. I get checksum errors after this procedure. I am using the ‘NonOS AT Bin 1.7.4 version’.
I have attached screenshots of the following:
- Flash tool and bin files to be loaded and their memory locations
- Error the modue throws after being flashed
- Guidance README document which comes within the folder of the firmware
Please help me point out where am I going wrong. Many thanks!
