It seems to work fine. The LPC-P2148 board should be similar to what you have (LPC-H2148), just with more stuffs. So maybe it is something strange with Olimex ARM-USM-TINY-H JTAG. I am using the original OpenOCD binaries from Freddie Chopin under 32bit Vista. The driver is the original Amontec driver (WHQL, based on FTDI's 2.06.00 version) and libusb-win32 filter driver 1.2.1.0. The two config files are also unmodified.

This could confirm that all FTDI FT2232 USB JTAG cables does not act the same ! Not the same layout, not the same input buffers, not the same output buffers, not the same signal protections and the same signal filters, and sure not the same price !
Anyway, it is a good point for the JTAGkey-2 ( http://www.amontec.com ) . Regards, Laurent _______________________________________________ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
