@soramame21 It looks like you encountered a windows "I can't tell the difference between .s and .S" issue when updating mbed-os. Could you delete the file mbed-os/rtos/TARGET_CORTEX/rtx5/TARGET_RTOS_M4_M7/TOOLCHAIN_ARM/irq_cm4f.s and check it out againg? it supposed to be /mbed-os/rtos/TARGET_CORTEX/rtx5/TARGET_RTOS_M4_M7/TOOLCHAIN_ARM/irq_cm4f.S

[theotherjimmy]

BTW, this becomes a problem, because the Arm assebler, armasm, only runs the C preprocessor on .S files, and not .s files. This strikes me as odd behavior, considering that it was originally developed for Windows, and windows does not distinguish....

@soramame21 .. can you check if #5149 helps ? please confirm..thanks!

Hey @ashok-rao. Thanks for mentioning that issue. It should have worked, but something is going awry with @soramame21's setup here. We have discussed what that patch brings to the table already, and it did not seem to work.

[soramame21]

@ashok-rao, @theotherjimmy, cc @MarceloSalazar Thanks for your comments. I had verified that the file is "irq_cm4f.S" although windows treats it as the same as "irq_cm4f.s".
I had applied the PR #5149, but doesn't help.
I don't install MinGW or Cygwin in my environment, just using windows command prompt.

PR #5149 will not help with any code issues, as it is purely documentation. I'm not sure why you attached the file.

The problem is that make is treating the file as if it were named irq_cm4f.s. There may be a workaround. Have you tried removing your mbed-os directory and deploying again? Windows may be doing something odd when git tells it to rename from irq_cm4f.s to irq_cm4f.S, and that can be avoided by creating the file with the name irq_cm4f.S.

[soramame21]

@theotherjimmy I'll try to remove mbed-os and deploy it.

[theotherjimmy]

@soramame21 Turns out Arm Compiler 5's behavior on assembly files is platform dependent! See the .S section of this page

[theotherjimmy]

That explains why I can't reproduce this, ever. I'm generally only using UNIX-like systems.
