→UART Recovery
=== UART Recovery ===
UART recovery does not requires any specialized hardware, apart a PC (Windows or Linux based) and a DB9 serial cross cable.
If not already available, configure [[Boot sequence (Naon)|Naon boot sequence]] to include UART boot.
To verify this, is enough to open a serial terminal (115200 8N1) and power on the board. If everything is correctly configured you should see a sequence of <code>CCC</code> on your screen.
Please follow [http://processors.wiki.ti.com/index.php/DM814x_AM387x_PSP_U-Boot#U-Boot_UART_support this instructions] on TI Wiki to load both 1st and 2nd stages of U-Boot.
When the 2nd stage is running follow [[Flashing Images (Naon)|this]] article for instructions on how to update U-Boot in flash
