[Computerbastler]

can you support the dsp chip interface is OnCE/JTAG-Interface

I would like to extract the internal memory from one
DSP56364

I do not think it is worth the time to develop this feature.

[Computerbastler]

t's a shame it would have been useful for repairing the sound cards as many people from the machine community would be helped if the memory contents came to see how later firmware can be reinstalled in the chip serial tabs but first you have to go to DSP firmware to disassemble it

[Computerbastler]

I do not think it is worth the time to develop this feature.

How much would it cost to retrofit the protocol for your work?

lol USB NT not wokking cheap jtag its woking for extrackt rom @usbbdm not will support this chip its schit

https://github.com/openocd-org/openocd/blob/master/tcl/target/dsp56321.cfg

It's a shame that now there are customers who didn't want to buy a USB NT and said they would have bought it, but if not, admin doesn't want to
Many people wanted to avoid buying the stick, but now you can forget about it if you can get it with a cheap 10€
Sadly, I thought the stick was really good just because admin is so stubborn. It would have been much nicer if the USB NT could do a lot more things, so the product is getting better and better, but there doesn't seem to be any interest in it

this its woking
