Like viewsat this is ARM CPU.I do not see any JTAG point of NANO2. So you should consider desoder the flash and program a good flash then solder back.jingleguy wrote:I have the datasheet for ARM946 RIC processor but I don't know how to upload it. Here is the link

here some info from ilink site when you try to convert Nano2 to Ilink
let me explain how it works
the loader does have a force load
however you really don't load nothing but to the ram
the boot decides to reject or accept the file that's loaded to ram
if accepts it than it writes it after it's been loaded to ram
if no you get an error message on the box
and get a good message on the loader
for apparently the loader is happy it completed the job and the boxis happy that you could not load the file

parallel
ejtag_tt is parallel port only,so get an old pc if yours doesn't have one.jingleguy wrote:Can I use USBJtagNT with Ejtag_tt software?
It works with conexant processors but you need a buffered jtag that is wired to match the ejtag_tt program.

speed
Be warned that the program takes forever; to erase and program a 2meg flash around 1 hour.That is why a buffered jtag is a must.
Make many backups of the flash and compare with a hex editor to make sure they are all identical before you erase any flash.

ejtag
The ejtag pinouts are different,so a store bought jtag cable would have to be modified.
I have the diagram in my archives somewhere.
Notice they only use 4 jtag lines instead of the usual 5
