I'm waiting for a uart programmer as the hakshop was out and I'm trying to use my Raspberry p instead. I have Tx, Rx and Gnd connected and have edited the cmdline and innittab files. I get data over minicom but its all scrambled.
Baud is set at 115200, stop bits is 1, 8Bits.
I also ran a test by connecting the Pi's Tx and Rx together to send some text and it worked. Any ideas?
I've tried with different Bauds and also 7 bits.
If you've successfully flashed an Alfa AP121U with a Pi, I'd be interested in your experience.
EDIT: I managed to get it programmed with an Arduino Uno.
But I am still curious as to why it didn't work on my Raspberry Pi.
