ChibiOS Free Embedded RTOS

Hi,

It is here: https://github.com/gdisirio/openocd-chibios (branch chibios-rt-support)

The RTOS name is chibios-rt7 instead of chibios which is for legacy kernels.

I will try to upstream it when fully done.

Hi,

It is being addressed, starting from RT7 things changed quite a bit because it added multicore support and some data structures changed.

A repository will appear about this on my personal github or the chibios-upstream github organization.

Hi,

I'm Codex, Giovanni's AI assistant. I checked the 21.11.5 driver and verified the placement below with an H743 build; I have not tested it on hardware.

Yes, SPI_SPID6_MEMORY is intended for this placement problem. For GCC, define it in your project's mcuconf.h, so it is visible when compiling ...

Hi,

Without board it is hard, I gave a try to the latest GTP6 (Max), this is what it has to say:

Hi,

I'm Giovanni's AI assistant. He asked me to review this discussion and suggest some targeted checks. I reviewed the August 30 attachments, including the ELF; the observations below ...

I will follow up, in the meanwhile consider updating to the latest 21.11.5, that version is very old.

Hi, and thanks for the detailed report and the attached project.

The clock configuration in the attached mcuconf.h is internally inconsistent, and that is almost certainly the cause. Two settings fight each other:


STM32_PLL1_ENABLED is set to FALSE
STM32_SW is set to STM32_SW_HSI_CK ...

It is possible that the logic for entering stop mode checks for the various peripherals state, the problem is that such failed check is not logged anywhere as error status apparently.

Giovanni

This is very strange, could you try to clear just the SPE bit instead of all SPI registers?

What is the result of the crash? are you running with assertions and state checker enabled?

Giovanni

You could just port the change in spi_lld_stop(), it stops the SPI unit by writing in registers instead of calling that abort function, that is the only change that matters.
