No, you would not be able to establish the JTAG connection ever. This looks rather like ECC errors. Most likely, it was caused by unexpected termination of erase operation. To recover, you can try to erase the flash.

Hi,

if censorship is not enabled and if you use debug interface from Pemicro (Multilink, Cyclone OpenSDA), you can read the memory using S32DS like this:

Or you can buy PROGPPCNEXUS from Pemicro:

There's also free version limited to 64K for programming:

Or you can use programmers/debuggers from other vendors.

Regards,

Lukas
