I am having trouble getting the serial console up and running on my WGU624 (running VxWorks /Nucleus /Delta Networks code). Console TXD is working, but console RCV is a problem. I have verified, using OCD Commander, that I can strobe characters into the on-chip UART, but I am not able to kick off an ISR to service the device. I have tried to reenable the UART FIFO, UART Rcv Data Irq - and this will set the MISC UART0 bit in the ISR [0xbc003010 = 0x10], but the interupt never gets serviced.

Here are the control areas (which I believe are OS agnostic) -

[I must say that OCD Commander is a pretty nifty tool. Kudos to Macraigor Systems for making this tool available.]

Without a serial console (and a reliable JTAG recovery mechanism) I am reluctant to flash the firmware.

Any ideas?

Is there anyone with expertise in this area who can help me to enable the CLI?

Great to hear that Kamikaze now supports the AR2315 wiSoc. Nice work.

However, a few us would really like to see OpenWrt on the WGU624. Can anyone tell me what is in the crticial path for this to happen?

I am assuming that ideally, the unit needs to have a functioning console port and a JTAG recovery mechanism to allow users to revert back to the factory firmware. Am I correct?

Is it absolutely necessary to rip out the Atheros/vxworks bootloader and install redboot?

Currently, I cannot get a CLI up and running (and have very little control over the TFTP downloads  - anything that gets downloaded, get's flashed if the loader likes the image)

I have also noticed that the "boot rom" executive, loader code, and decompression routine are not included in the vendor update packages, so they need to be recovered from flash or dumped from RAM.

So, who needs to do what work to make this happen and what can I do to assist, now that I've gotten my feet wet?
