I have two remote gsm switches. Their developing company has stopped operations and both the devices are now not working. I opened those devices and found onboard atmega328p paired with sim900 gsm module. There is one mini usb port that and its data pins are connected to tx/rx pins of atmega328p. I am trying to program this board with my own code to make it work again. I tried to connect atmega with ch340 usb to ttl adapter but not able to program. Can anybody please help me to reprogram this board.

No: it's about an AVR 8-bit microcontroller - not even an ARM architecture at all!
https://www.avrfreaks.net/ would be the place to go.
Andy Neil I just hesitated to say it lol :)
No, it doesn't belong here at all - it has nothing whatsoever to do with ARM.
Again, https://www.avrfreaks.net/ would be the place to go - the clue is in the name...
For sure Andy lol, but we can answer, and help it anyway to look at the good way :)
Realised landed at wrong place. Please delete this question. Thanks.
