Hello,
I found the bug by myself. I have made a patch file to correct it.
Is it possible to incorporate this patch into the source code?

First I want to say that I am very happy with the OpenOCD-software! I
like it very much.
I have a Chameleon POD from Amontec. This dongle can be programmed to
act as a Wiggler-cable, but also as a JTAG Accelerator interface.
I use it in combination with an ARM processor and a FPGA. Both are
supplied by Propox.
When I use the Wiggler JTAG interface, I get the following information:
Info : JTAG tap: at91sam9260.cpu tap/device found: 0x0792603f
(Manufacturer: 0x01f, Part: 0x7926, Version: 0x0)
When I use the Amontec JTAG Accelerator Interface, I get the following
information:
Info : JTAG tap: at91sam9260.cpu tap/device found: 0x03c9301f
(Manufacturer: 0x00f, Part: 0x3c93, Version: 0x0)
It looks like the whole word is shifted 1 bit. I think the Wiggler
interface is correct.
I also tried my FPGA module and got the following ID's:
Manuf. Chip wiggler amtjtagaccel
Processor: Atmel AT91SAM9260 0x0792603f 0x03c9301f
Platform Flash: Xilinx XCF01S 0xF5044093 0x7A822049
FPGA: Xilinx XC3S200 0x01414093 0x80A0A049
The ID of the FPGA is not only shifted 1 bit to the right, but is also
OR-ed with 0x80000000
The wiggler ID is correct
Can you correct this?
Kind regards,
