Hi! Is it possible to detect which cpu (out of a given set) is actually connected to my jtag-adapter? For example, if I have a board that can be build with a set of pin-compatible cpus (like at91sam7x128, at91sam7x256, at91sam7x512), can I detect which one is actually present on the board?
http://support.atmel.no/bin/customer?=&action=viewKbEntry&id=188 says "None of the AT91 devices feature a JTAG chip ID." OTOH, http://www.atmel.com/dyn/resources/prod_documents/doc6120.pdf lists some IDs: • PART NUMBER[27:12]: Product Part Number AT91SAM7X512: 0x5B18 AT91SAM7X256: 0x5B17 AT91SAM7X128: 0x5B16 • MANUFACTURER IDENTITY[11:1] Set to 0x01F. Bit[0] Required by IEEE Std. 1149.1. Set to 0x1. AT91SAM7X512: JTAG ID Code value is 05B1_803F AT91SAM7X256: JTAG ID Code value is 05B1_703F AT91SAM7X128: JTAG ID Code value is 05B1_303F So, is it actually possible?
