Thanks Oleksij,
I soldered 49th how suggested in wikidevi, I modified the firmware adding adf_os_print.
When I opened minicom I set upped the serial port (ttyUSB0) with 19200 baudrate.
However I didn’t see any output. So I read the data sheet and I found some different how reported in wikiDevi.
In wikidevi the 49th pin is GPIO8 instead in data sheet is GPIO10. The 21st pin is the GPIO8 -General purpose and multiplexed serial input data from an SPI device-.
BTW,I was watching the solder made by Oleksij and I recognized that the chipset is ar7010 and the pin was 48th pin (GPIO8)
Do I solder the 21st for my a r9721?
Thanks a lot
Matteo
