Openocd Stm32f4
having trouble getting multiple software breakpoints to work. I am just starting to gdb openocd debugging work with the NXP LPC21XX parts and am using Eclipse, OpenOCD and Yagarto and a Keil MCB2140 (LPC2148). I have a
Arm-none-eabi-gdb Tutorial
very simple test program that will blink an LED. If I load the program into Flash, I can use two breakpoints. If I try to set more breakpoints I get a message that says stm32 openocd "Could not insert hardware breakpoints: You may have requested too many hardware breakpoints/watchpoints" If I load the program into RAM, I can only set one breakpoint. When I start executing with more than one breakpoint, I get an error that says "Cannot insert breakpoint 2. Error accessing memory address 0x400001a0: (undocumented errno -1)" When debuggin in RAM, I use the following gdb initialize commands: ------------------ target remote localhost:3333 localhost:3333: the system tried to join a drive to a directory on a joined drive. monitor reset monitor sleep 500 monitor poll monitor soft_reset_halt monitor arm7_9 sw_bkpts enable monitor mww 0xE01FC040 0x0002 monitor mdw 0xE01FC040 # needed for gdb 6.8 and higher set mem inaccessible-by-default off load break main continue ------------------- Am I correct in thinking I should be able to set lots of breakpoints when running in RAM? If so, what am I doing wrong? Thanks in advance, MarkAn Engineer's Guide to the LPC2100 SeriesFree Download Posted by Gaspar Pollano ●May 23, 2008Hi Mark!, Im also using LPC2148 with ECLPISE. When you debug on FLASH there is a maximum of two breakpoints at the same time. When you debug on RAM there is no limit. I assume you are using diferents linker scripts to load the program into FLASH and RAM, since the locations are diferent. Im using this for a while with no problems. This are my gdb initialize commands: (For RAM): ---- target remote localhost:3333 monitor reset monitor sleep 500 monitor poll monitor soft_reset_halt monitor arm7_9 sw_bkpts enable monitor mww 0xE01FC040 0x0002 monitor mdw 0xE01FC040 break main load continue ----- And the script to the OpenOCD is: ------ #daemon configuration telnet_port 4444 gdb_port 3333 #interface interface ft2232 ft2232_device_desc "Olimex OpenOCD JTAG A" ft2232_layout
