Is there any hw interface that may set hw breakpoints on flash and also may be interfaced with low cost debuggers as Insight?

They can be accessed from Insight. I have the following in my .gdbinit file. =================================================================================== # Define some macros for setting & clearing breakpoints using the EmbeddedICE logic define ib monitor reg w$arg0av = $arg1 monitor reg w$arg0am = 1 monitor reg w$arg0dv = 0 monitor reg w$arg0dm = 0xFFFFFFFF monitor reg w$arg0cv = 0x100 monitor reg w$arg0cm = 0xFFFFFEF7 end document ib ib <idx> <addr> Configures hardware Instruction Breakpoint <idx> (0 or 1 for ARM7TDMI) to break at address <addr>. To disable the breakpoint, set <addr> to some address that won't be executed or use 'db <idx>'. end define db monitor reg w$arg0av = 0xFFFFFFFF monitor reg w$arg0am = 1 monitor reg w$arg0dv = 0 monitor reg w$arg0dm = 0xFFFFFFFF monitor reg w$arg0cv = 0x100 monitor reg w$arg0cm = 0xFFFFFEF7 end document db db <idx> Disable hardware instruction Breakpoint <idx> by setting it to 0xFFFFFFFF end ==================================================================================== I didn't write the macros but have found them useful. Other ARM toolsets like CrossWorks for ARM by Rowley have debuggers which support the hardware breakpoints much more cleanly than the above gdb macros Regards -Bill Knight R O SoftWare & http://www.theARMPatch.com

Just in case you were wondering who authored those GDB scripts, it was me!
You can get all the info on how they work, and the original scripts from
my site at:

Thanks Rod. I tucked them inot my gdbinit file quite a while back and unfortunately, promptly forgot who wrote them. They have been very helpful in getting Insight to debug flash based code. -Bill
