I'm new to openOCD and just tried to make the latest version from Git. My
openOCD target is bare-metal ARM. The end of the log is as follows:
/bin/sh ../../libtool --tag=CC --mode=compile gcc -std=gnu99

After investigating the source file, here are the two offending sections:
void breakpoint_remove_internal(struct target *target, uint32_t address)
{
struct breakpoint *breakpoint = target->breakpoints;
struct breakpoint **breakpoint_p = &target->breakpoints; (line 162)
while (breakpoint)
{
if (breakpoint->address == address)
break;
breakpoint_p = &breakpoint->next;
breakpoint = breakpoint->next;
}
if (breakpoint)
{
breakpoint_free(target, breakpoint);
}
else
{
LOG_ERROR("no breakpoint at address 0x%8.8" PRIx32 " found", address);
}
}
void watchpoint_remove(struct target *target, uint32_t address)
{
struct watchpoint *watchpoint = target->watchpoints;
struct watchpoint **watchpoint_p = &target->watchpoints; (line 335)
while (watchpoint)
{
if (watchpoint->address == address)
break;
watchpoint_p = &watchpoint->next;
watchpoint = watchpoint->next;
}
if (watchpoint)
{
watchpoint_free(target, watchpoint);
}
else
{
LOG_ERROR("no watchpoint at address 0x%8.8" PRIx32 " found", address);
}
}
I don't understand the error, since it looks like struct watchpoint **
watchpoint_p is being used in the while loop. How can I resolve this?
Best regards,
Andrew Ashworth
