Same here. I am running Release 1.7 build 14. I frequently get into a
mode where no breakpoints are shown but CrossWorks reports no hardware
breakpoints available. I am using CrossConnect JTAG debugger.

Only recourse is to restart CrossWorks.

Any on else seeing this or have a solution?

I've seen this too, on occasion.

I believe that sometimes, to do a break on a line of C code requires a
breakpoint at TWO ASM instructions. Check your disassembly.

Also worth trying, is to clear ALL breakpoints (not one by one), then
try to set them again. "ctrl-shift-F9" should clear all of them.

Having only two available can be a pain sometimes.

If it's any consolation, this sometimes happens with Eclipse too. Delete
all doesn't work either; it's like it permanently loses track of a
hardware interrupt and restarting is the only option. The most common is
to lose 1 interrupt and then only have 1 to play with (which means
removing all ints so you can use the one remaining to single step...but
it's sometimes worth limping on if you've got somewhere important.
Luckily it doesn't happen too often.

Solution would be to wait for Crossworks 2, which will have
reprogramming flash segments to allow many interrupts.

It may not fix your problems, but I would always download and install
the latest version of the software. The latest build of Crossworks is
1.7build17. Also if you are using the crossconnect Jtag debugger make
sure this has the lastest firmware.

Note you can install the newer version of Crossworks in a different
directory so it will not overwrite you existing install.

Cheers
