Hello.
I need to test PCB's with XPC755BPX300LD processor in BGA. This board have many other peripheral IC such as PCI-/Memory Contr. , PCI to cPCI Bridge , Ethernet Controller , SCSI Controller e.t.c. All PCB's is the same and at all Linux doesn’t start, but I am sure that FLASH memory with OS is fine. So I want to check only processor. I know that pcb has JTAG, because XPC755BPX300LD support IEEE 1149.1 JTAG interface and allow LSSD scan design. I know that this chip is old and it work with external FLASH, so JTAG very often not use.
I want check which PCB board’s has working XPC, so for this purpose I want to scan JTAG chain and detect device's.
The main problem is that, as I know, the Motorola company is not exist now and has not any support (only very superficial information). So I can’t find any JTAG programmer for this device. May be I can use any standard JTAG programmer with basic IEEE 1149.1 command’s – but I don’t know which command supported by XPC755BPX300LD. Please help: how I can scan JTAG?
Best regard’s!
