Hi @boraozgen
I've already raised this issue internally as I've met this issue with STM32duino. I've made a patch while waiting for it to be fixed in the official release. https://github.com/stm32duino/Arduino_Core_STM32/blob/master/CI/utils/patch/HAL/F4/0001-F4-Fix-HAL_RCC_USART3-definition-for-STM32F412Cx.patch
ST Internal Reference: 82376
Great, thank you for the information. Looking forward to the next release.
@boraozgen You could propose a patch in mbed-os repo, I will review and it could be merged there.
Just FYI, issue comes from the fact STM32F412Cx define is to manage the STM32F412 UFQFPN48 part numbers, for these devices it have a hardware limitation (Note 2 in datasheet page 15):
Limited application for the USART3 since RX is not available for the UFQFPN48.
So there is only the USART3 TX available which van be used for half duplex.

Looking forward to the next release.
About this I cannot guarantee that a fix will be in the next release. I'm only a user of the HAL and CMSIS for the STM32duino GitHub organization 😉 I would just inform that this issue was already tracked internally and the fix I'm using temporarily.
I leave @ALABSTM or @RKOUSTM comment on this.
Hi @boraozgen,
Thank you for your contribution. As @fpistm said the issue has been tracked and fixed internally. The fix will be made available in the frame of a future release. Unfortunately, we cannot share a date for the moment. Stay tuned and thank you once more for your contribution and for your patience.
Thank you also @fpistm, for your contribution and for your reactivity as well as for the given clarifications.
With regards,

Reopened till the fix is released on GitHub.
Hi @boraozgen,
I hope you are fine. The issue you reported has been fixed in the frame of version v1.26.0 of the STM32CubeF4 published recently on GitHub.
Thank you again for having reported.

Describe the set-up Custom board with STM32F412CG. Mbed OS 6.2.0 with GCC ARM 9-2020-q2-update
Describe the bug Cannot link
serial_api
, since there is a contradiction between CMSIS and HAL:In CMSIS
stm32f412cx.h
USART3_BASE
is defined.In RCC HAL, USART3 functions are not defined for
STM32F412Cx
.https://github.com/STMicroelectronics/STM32CubeF4/blob/9f5ea7421d22c724516d00218b350d1e09a54a2c/Drivers/STM32F4xx_HAL_Driver/Inc/stm32f4xx_hal_rcc_ex.h#L5448-L5449
This causes linker issues for example when trying to link
serial_api.o
of the STM HAL in Mbed OS due to these lines:https://github.com/ARMmbed/mbed-os/blob/master/targets/TARGET_STM/serial_api.c#L246-L252
I believe this is not an Mbed issue but an HAL issue.
How To Reproduce Try to build an Mbed OS 6.2.0 project for STM32F412CG.
Additional context It is fixed when
STM32F412Cx
is added to the conditions for all USART3 functions.Screenshots N.a.
