Bug after commit 12752  Topic is solved

After commit #12752(Fixed bug #1027), I'm unable to compile my project with CH_DBG_ENABLE_STACK_CHECK enabled.

Hi,

I am unable to reproduce the problem.

"MPU" is exported by CMSIS headers. Are you using those included with ChibiOS?

Well, I believe so, I did not change anything in my build since this commit.

Here is my makefile, maybe something missing:

Could you try to add stack check to one of the M4 demos and try to compile? just to check if it is something missing or an environment difference.

You are also specifying PORT_ENABLE_GUARD_PAGES, right?

Building the demos/STM32/RT-STM32F429-DISCOVERY works OK when enabling CH_DBG_ENABLE_STACK_CHECK.

No, I'm not specifying PORT_ENABLE_GUARD_PAGES. It is FALSE per default.

Same error as mine when building MapleMini demo:

Ah OK, now I can reproduce the problem thanks, it is an error in the conditional expression.

Code: Select all

#if (CH_DBG_ENABLE_STACK_CHECK == TRUE) ||                                  \
    (PORT_ENABLE_GUARD_PAGES == TRUE) ||                                    \
    defined(__DOXYGEN__)
/**
 * @brief   Setting up MPU region for the current thread.
 */
void _port_set_region(void) {

  mpuSetRegionAddress(PORT_USE_MPU_REGION,
                      chThdGetSelfX()->wabase);
}
#endif


It should be an &&...

It is only triggered when the device does not have an MPU, I will open a ticket about this.
