It’s not something wrong with the 4809 really it’s that it’s not working when I have to disconnected from the nano programmer. I am using a nano with jtag to program my atmega4809 boards. However, SD works perfectly fine when I use it while still connected to the programmer, but when I run the board on it’s own the SD doesn’t work at all. What’s up with that? Why would that make any difference? Shouldn’t the atmega4809 being running exactly the same way either way? The nano shouldn’t have any influence on anything aside from programming. What gives? Please help.
