JTAG-Serial Info

Serial Pinouts

• Location: unused 6 pin header in middle of CPU PCB.
• Pintout: From RAM-side of PCB, pins read:

 ©  ©  ©  ®  ®  ®
GND TX RX -  -  -

• Special Magic:

Normally, Linux won't support a local getty / console.

So, in u-boot, use this to boot:

if test "kernel1" = "${ACTIVATED_KERNEL_NAME}"; 
then setenv image_address 0xf80000; 
setenv bootargs "${bootargs} root=rootfs1 debug=1"; 
else setenv bootargs "${bootargs} root=rootfs0 debug=1"; 
fi; sf read ${loadaddr} ${image_address} 0xE00000; bootm
