First I messed up the WiFi configuration so I now have a connection through the UART and reset the configuration to factory with firstboot.
I have compiled a image following http://vonger.cn/?p=1585 but before I start flashing I want to ensure I can get into U boot to recover if things go badly.
I have tried using both picocom and minicom with 57600 8N1 settings but I can't get into U-Boot, the first output when I apply power is:
- Code: Select all
Welcome to minicom 2.6.1
OPTIONS: I18n

Port /dev/ttyUSB0
Press CTRL-A Z for help on special keys

[ 0.430000] 10000c00.uartlite: ttyS0 at MMIO 0x10000c00 (irq = 20, base_baudA
Just blindly typing "x" when powering up doesn't stop the boot process either.
How do I get the Uboot prompt?
