cc @theotherjimmy I suspect this: not running in the make armcc5 ?

[theotherjimmy]

@0xc0170 This looks like a problem with the name of the file. It should end in ".S" not ".s"

[ashok-rao]

@theotherjimmy .. file names are correct in \mbed-os\rtos\rtx5\TARGET_CORTEX_M\TARGET_RTOS_M4_M7\TOOLCHAIN_XXX as seen below:

@ashok-rao Windows filesystems are case insensitive, so if this was an update, git might have not been able to move the files correctly.

[theotherjimmy]

@ashok-rao Could you try a fresh clone starting at 5.5.0-rc3?

[MarceloSalazar]

@ashok-rao could you test this please

[ashok-rao]

@theotherjimmy .. I can still see the issue with 5.5.1 as well. I started with a fresh clone of 5.5.1..also tried with 5.5.0 too. Below are some details:
SHA's I'm currently using:

mbed-os-example-fat-filesystem (f2017e51867a)
`- mbed-os (c9e63f14085f)

Steps:

1. mbed export -i make_armc5 -m NUCLEO_F746ZG
2. make clean
3. make

Also, master branch of example still pointing to 5.4.7 .. are we planning to update this to 5.5.1?
FYI @MarceloSalazar

[MarceloSalazar]

Same problem in 5.6 rc2

@adbridge @theotherjimmy

[theotherjimmy]

And it's not going to go away until ARMmbed/mbed-os#5166 is merged. This is a bug in Arm Compiler 5 that we have to work around.

[sg-]

Did we find out why the build log shows "Assemble: irq_cm4f.s" while the dir actions show 14/06/2017 10:21 6,082 irq_cm4f.S What terminal was the make command executed in?

[ashok-rao]

@sg- , Windows filesystems are case in-sensitive apparently (#13 (comment) ). So, a search for *.s or *.S, leads to same results. Standard Windows terminal was used for the make cmd..
