Hi, Im trying to get openocd to work with a Jlink and an STM32F102R4 processor. When I connect to the device and issue a flash probe 0, I get the following output:
> flash probe 0 device id = 0x10006412 STM32 flash size failed, probe inaccurate - assuming 32k flash flash size = 32kbytes flash 'stm32x' found at 0x08000000 > Here is the output from openocd: 500 kHz Info : J-Link ARM V6 compiled Feb 17 2009 16:41:40 Info : Vref = 3.267 TCK = 1 TDI = 0 TDO = 1 TMS = 0 SRST = 1 TRST = 1 Info : J-Link JTAG Interface ready Info : JTAG tap: stm32.cpu tap/device found: 0x3ba00477 (Manufacturer: 0x23b, Part: 0xba00, Version: 0x3) Info : JTAG Tap/device matched Info : JTAG tap: stm32.bs tap/device found: 0x06412041 (Manufacturer: 0x020, Part: 0x6412, Version: 0x0) Info : JTAG Tap/device matched Warn : no telnet port specified, using default port 4444 Warn : no gdb port specified, using default port 3333 Warn : no tcl port specified, using default port 6666 Info : accepting 'telnet' connection from 0 Info : device id = 0x10006412 Warn : STM32 flash size failed, probe inaccurate - assuming 32k flash Info : flash size = 32kbytes flash 'stm32x' found at 0x08000000 The device I am connected to only has 16K of flash, so this fails when I try to program the part. The source is checked out from svn. If I add "flash bank stm32x 0x08000000 0x4000 0 0 0" to my config file, I still have the same issue. When I try to program the device, I get the following output: auto erase enabled Info : device id = 0x10006412 Warn : STM32 flash size failed, probe inaccurate - assuming 32k flash Info : flash size = 32kbytes Warn : writing 32768 bytes only - as image section is 536871180 bytes and bank is only 32768 bytes Warn : not enough working area available(requested 16384, free 16336) Error: jlink_jtag_write illegal out_length=3262 (max=2048) Error: usb_bulk_write failed (requested=3262, result=-1) Error: jlink_tap_execute, wrong result -107 (expected 1629) Error: jlink_tap_append_step: overflow Segmentation fault Thanks, Ed Despard _______________________________________________ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
