Hello!

I am using KEIL MDK 5 and it is compiling very very slow.

CubeMX v4.24

STM32CubeF4 v4.19.

Any ideas ??

Thanks

Sasha

Already tested with ll library, and same problem.

I am talking about more than 2 minutes compiling time for 8k code size!!

This is not reasonable at all and it wasn't like that before.

Try to ask Keil support as well

KEIL is not the problem. Someone already asked it. see this discussion:

Hello,

problem on your side is due to the fact thatstm32fxxxxx.h files (files with bit descriptions, peripheral memory addresses) have been enlarged by 2 additional definitions for every bit, and can go up to 20k lines of code in F7 family:

/* These 2 are new for every bit */
#define PERIPH_REG_BIT_Pos 1
#define PERIPH_REG_BIT_Msk (1 << PERIPH_REG_BIT_Pos)
/* This one is old */
#define PERIPH_REG_BIT PERIPD_REG_BIT_Msk�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?

Keil cannot handle (apparently) big files for include. Similar problem does not affect GCC or IAR.

Best regards,

Tilen

Change Arm compiler to use V6, default is V5.

You can modify it on Project Option → Target → Code Generation.
