Hi, Ok I have tried this. I get a fast image download, but I have slow debugging as the clock seems to get reset back to 10khz again .. (The JTAG clock gets limited to 6Mhz by the Turlelizer2 hardware ..)
This is the dump from gdb output .. ------------------------------------------ target remote localhost:3333 0x00000000 in g_pfnVectors () mon reset init 10 kHz JTAG tap: lpc1766.cpu tap/device found: 0x4ba00477 (mfg: 0x23b, part: 0xba00, ver: 0x4) target state: halted target halted due to debug-request, current mode: Thread xPSR: 0x01000000 pc: 0x1fff0080 msp: 0x10001ffc 6000 kHz load Loading section .text, size 0x8383 lma 0x0 Loading section .data, size 0x211 lma 0x8383 Start address 0xcc, load size 34196 Transfer rate: 7 KB/sec, 8549 bytes/write. mon reset halt 10 kHz JTAG tap: lpc1766.cpu tap/device found: 0x4ba00477 (mfg: 0x23b, part: 0xba00, ver: 0x4) target state: halted target halted due to debug-request, current mode: Thread xPSR: 0x01000000 pc: 0x1fff0080 msp: 0x10001ffc thb main Hardware assisted breakpoint 1 at 0x29ae: file main.c, line 79. --------------------------------------------- Shouldn't the clock stay at the high rate?

With the currect reset sequence I am using? Look at board/mcb1700.cfg Debugging is probably stable at higher clock rates once the PLL is running. -- Øyvind Harboe US toll free 1-866-980-3434 / International +47 51 63 25 00 http://www.zylin.com/zy1000.html ARM7 ARM9 ARM11 XScale Cortex JTAG debugger and flash programmer _______________________________________________ Openocd-development mailing list [email protected] https://lists.berlios.de/mailman/listinfo/openocd-development
