Mismatch STM32H747I-DISCO board configuration in STM32CubeMX .

[ramkumarkoppu]

As per the section 5.2.3 of the STM32H747I-DISCO board user manual, the default configuration of the hardware is to use SMPS mode but the default mode generated by STM32CubeMX when you select STM32H747I-DISCO board is LDO. Because of this mismatch, the board is bricked.

ST should have used the same power supply configuration in both the hardware board and default CubeMX configuration.

​Hello @ramkumarkoppu​ ,

Thanks for your feedback,

CubeMX gives you the choice to choose which supply source you like , so  you can change this parameter under RCC configuration .

Best regards,

Khouloud

Hi @Khouloud ZEMMELI​ There is no option in CubeMX specifically for PWR_DIRECT_SMPS_SUPPLY.

​You're right @ramkumarkoppu​ this issue has been fixed and it will be available in the 5.4.0 CubeMX version.

Best regards,

Khouloud.

And also Core Boot selection is grayed out. I can't see option in CubeMX to select CPU core. Is this something will be available in the next version?

[Khouloud ZEMMELI]

For RCC both cortexs are available ​.

[ramkumarkoppu]

I mean, In the dual core micro controller STM32H747, In the CubeMX, we don't have option to enable just one core and disable the other. Is it something possible with the current version of CubeMX ?

[Khouloud ZEMMELI]

​Ah, no this's not possible for the moment.

[ramkumarkoppu]

Can you please add this option in the next version. It will be handy.

[Khouloud ZEMMELI]

​I'll be share your request with the team .

This will be internally checked.

Best Regards,

Khouloud.
