How are things now with the transfer of the platform STR8132?
In particular, for devices Agestar NCB3AST/NSB3AS/NSB3AST/NSB3AS1T.

OpenWRT has support for these devices as it was recently added. I have successfully built OpenWRT and put it onto  a NS-K330 from DealExtreme. You will have to built it yourself as there is no prebuilt images as yet. There is an option in menuconfig to enable the CNS21xx selection.
Goto 'advanced configuration options' then 'show broken platforms/packages'. You'll then see CNS21xx appear under 'target system' in the root menu. I've haven't tried the latest trunk, so this may have all been fixed by now. I'm a few months behind.

I've been trying to get a 8MB flash chip working on my device (standard is 4MB) - I've got OpenWRT happily working with it but I need to rebuilt the u-boot bootloader as it doesn't detect the brand of chip I'm using and therefore won't boot from it. I've built u-boot from the source package of snakeos but only succeed in bricking my unit. My flash is on a socket so I can easily recover. BTW I'm using a SST brand SST25VF064 flash chip. If anyone can assist with the building of das-uboot for the NS-K330, I'd be much obliged.

The discussion might have continued from here.
