I compared my cu output with that from randominsano (ri).

These were the differences I thought might be relevant:

Code:
me: U-Boot 1.1.4 (Mar  9 2010 - 16:28:25)
ri: U-Boot 1.1.4 (Jun 22 2010 - 14:55:31)

I'm pretty sure my device is the original firmware as shipped.
Code:
me:
Kernel command line: noinitrd root=/dev/mtdblock4 rw rootfstype=yaffs init=/linuxrc console=ttySAC0 controller=2 PA_BB=29 PA_BT=1 FS_BB=30 FS_BT=1280 AP_BB=1310 AP_BT=8 US_BB=1318 US_BT=6874 UVer=ntx-600em-v2.6

ri:
Kernel command line: noinitrd root=/dev/mtdblock4 rw rootfstype=yaffs init=uxrc console=ttySAC0 controller=2 PA_BB=29 PA_BT=1 FS_BB=30 FS_BT=1280 AP_BB=1310 AP_BT=8 US_BB=1318 US_BT=6874 UVer=ntx-600em-v2.6

init=/linuxrc vs
init=uxrc
Code:
me:
PORT: 4034920448 baud 115200 uart: ulcon = 0x00000003, ucon = 0x000003c5, ufcon = 0x00000051 ubrdiv 0x00000023 umcon 0x00000000

ri:
PORT: 4034920448 baud 115200 uart: ulcon = 0x00000003, ucon = 0x000003c5, ufcon = 0x00000051 ubrdiv 0x0023 umcon 0x00000000

ubrdiv 0x00000023 vs 0x0023
Code:
me:
Warning: unable to open an initial console.
Failed to execute /linuxrc.  Attempting defaults...

ri:
PORT: 4034920448 baud 115200 uart: ulcon = 0x00000003, ucon = 0x000003c5, ufcon = 0x00000051 ubrdiv 0x00000023 umcon 0x00000000
PORT: 4034920448 baud 115200 uart: ulcon = 0x00000003, ucon = 0x000003c5, ufcon = 0x00000051 ubrdiv 0x00000023 umcon 0x00000000
PORT: 4034920448 baud 115200 uart: ulcon = 0x00000003, ucon = 0x000003c5, ufcon = 0x00000051 ubrdiv 0x00000023 umcon 0x00000000
I'm not sure what to make of these differences. Hoping someone with more experience with these devices has some suggestions.
