md5 of file does not match data in flash

[Samir Arishy]

This is esp01 and using tasmotizer. Keep getting this error. I used esptools:
esptool --chip esp8266 --port COM4 --baud 115200 --after hard_reset erase_flashI

I also used:

esptool write_flash_status --non-volatile 0

When flashing  using Tasmotizer. I noticed when easing the memeory it stopped at 50% them resumed. After flashing I get the above error message..

When I used the last command above I got:
Connecting....
Detecting chip type... ESP8266
Chip is ESP8266EX
Features: WiFi
Crystal is 26MHz
MAC: e8:68:e7:80:0b:f5
Uploading stub...
Running stub...
Stub running...
Initial flash status: 0x0000
Setting flash status: 0x0000
After flash status:   0x0000
Hard resetting via RTS pin...
 Your help will be greatly appreciated

Why are you trying to write to the flash status bits?  Be careful doing that without researching the effect.

The first command just erased the programme area of the flash memory.  Is that what you intend?  If so try again but end the command after erase_flash and delete the trailing "l".

Why are you not using the web installer?

read_flash 0 ALL flash_contents.bin

This outputs the flash contents to a file.  You need to specify baud and port as you know.  Go slow on the baudrate if you have a bad quality or cheap serial converter

The commands I mentioned are taken from people who had the same problem as me. I did not try to play with status intentionally. All I wanted was to flash tasmota to the esp01. I will try the web installer and let you know. By the way do you know of esptool command to TEST the flash memory to see if it is OK?

You can set up the WiFi parameters via the web installer. 

Or just reboot and you should see the tasmota WiFi network which you can join and set up the WiFi ssid

Great tip. To dump the content and if there are errors it will tell ..I presume.  As for the web installer , to my happy surprise it went with no errors. But I am stuck. I cannot see it when I arp -a. I know the mac address ( e8:....:0c) but it is not showing. I assume I need to setup up wifi; but my w11 does it see it

Then try connecting to the tasmota WiFi network
