Bus Blaster JTAG debugger / BPv4 CPLD programming
hi,

today the BBv4 is arrived.

I installed D2xx driver and win 7 x64 recognize it (obviously 2 interface).
I attached to my target (a st20  CPU) but I can' recognize the IDCODE.
I use the FTDI delphi program:

USB to a JTAG TAP Interface using FT2232H

I have another FT2232h device

and it can recognize the idcode.

I think that the HW is pretty similiar.
Do you have any idea why BB doesn't work?

have I to download some svf into CPLD?

regards

Open Bench Logic Sniffer / Sniff SDRAM protocol
Hi,

I was wondering if OLS is able to sniff SDRAM protocol.
I have a board with an ARM CPU connected to a 16 mb sdram chip 143 mhz (hynix HY57V283220T).
What I just need is to sniff the bus in order to dump what CPU read/ write.
In this way I could access directly to code loaded from flash (it's encrypted there).

Someone know if OLS can accomplish these velocities?

If not, what kind of logic analyzer I have to see?

regards
