ChibiOS Free Embedded RTOS

Found it: It's the USE_LTO setting in the Makefile. If enabled, cfmconfig is optimized away. Is there a way to protect against this? EDIT: This can be fixed for gcc by adding 'used' attribute: __attribute__ ((used,section(".cfmconfig"))) in os/hal/ports/KINETIS/KL2x/hal_lld.c:40 But I don'...

I'm probably having trouble with this. Compiling ChibiOS git /demos/KINETIS/RT-TEENSY3 with gcc (4.9.3 20150529) gives .cfmprotect *(.cfmconfig) 0x0000000000000100 _text = . in build/ch.map and /demos/KINETIS/RT-FREEDOM-KL25Z .cfmprotect *(.cfmconfig) 0x00000000000000c0 _text = . in build/ch.map. Th...

Here's a patch (moves things in MK20DX128VLF5.ld past bootloader; adjusts Makefiles for MCHCK demos), to be applied to 3.0.1. Tested on a MCHCK with mk20dx128vlf5 chip, but not on the official mchck bootloader: I can't make that one compile into the allocated 3072 bytes (I can do it for mk20dx32vlf...

OK, I've tried to figure this out (but please bear in mind that I'm an ARM newbie). Freescale K20 chips seem to have FlexRAM (a piece of memory that can be used either as EEPROM or RAM). The configuration for this is stored at 0x400, 16 bytes total. Described in the K20 reference manual , page 503. ...

Sorry to resurrect an old thread - did you figure out the flashcfg bit? I would be interested in having the MCHCK support finished...

Thanks! Works now.

Repo organisation: I'm just happy you did the usb driver, so whatever works for you ;) Maybe once the driver is more "complete", it could be moved to the main or contrib repo :) So - I tried your USB_HID and USB_SERIAL examples, they work :) I also tried plugging it into my own "usb_h...

About the community repo: I actually like when it's side-to-side with chibios proper, and the projects pull files from both, depending on what's required - have a look at some demos in chibios-contrib. Having two forks of chibios proper (e.g. yours and the official one) requires me to keep track of ...

Thanks! And you're right, silly me (v6m). But even with that it's the same error...

Hi, The examples in testhal/KINETIS don't compile for me, maybe they haven't been updated to 3.0.1? Makefile:90: ../../../os/rt/ports/ARMCMx/compilers/GCC/mk/port_kl2x.mk: No such file or directory make: *** No rule to make target `../../../os/rt/ports/ARMCMx/compilers/GCC/mk/port_kl2x.mk'. Stop.
