frdmk64/frdmk66 /usb_examples/*/freertos missing fsl_os_abstraction_free_rtos.c

[karlp]

At present, the CMakeLists.txt file selects the component_osa component, see: https://github.com/nxp-mcuxpresso/mcux-sdk-examples/blob/main/frdmk66f/usb_examples/usb_device_audio_generator/freertos/armgcc/CMakeLists.txt#L120

This means they all[1] fail to compile with a missing implementation of OSA_ExitCritical

Now, another freertos example for the K66, https://github.com/nxp-mcuxpresso/mcux-sdk-examples/blob/main/frdmk66f/component_examples/log/freertos/armgcc/CMakeLists.txt#L79 instead selects thecomponent_osa_free_rtos

That example builds, and indeed, using that component in the usb examples fixes them all.

however the https://github.com/nxp-mcuxpresso/mcux-sdk/blob/main/components/osa/component_osa.cmake file over in core, attempts to handle lots of different CPUs directly, but does not have any IF blocks for K66, so that fails.

Either please, at your desire, add the IF blocks to the component_osa.cmake in core, or, in this repo, switch all the examples that use component_osa to use component_osa_free_rtos

Using the script below, this apparently only affects frmdk64, frdmk66, and rdrw612bga

$ ack --type=cmake 'include(component_osa)' /usb_examples//freertos | cut -d'/' -f1-3

At least under K66, the following examples use free_rtos explicit form

frdmk66f/usb_examples/usb_device_composite_cdc_msc_disk
frdmk66f/usb_examples/usb_device_msc_disk
frdmk66f/usb_examples/usb_device_mtp
frdmk66f/usb_examples/usb_host_audio_recorder

And the remainder all use the broken form, and fail to compile
