GPIOS for CSI on stm32n6

[darla14]

Hello,

while configuring the CSI interface for camera , on its enablement in the STM32CubeMX why I can’t see the GPIOs corresponding to it in the flip section? 
does it has any dependency on any other peripheral?or clock setting?
under the configuration it says warning: this peripheral has no parameters to be configured.

Unlike in any other peripheral like I2C or  SPI where I can see the corresponding GPIO i am checking this on STM32N657X0HxQ .

regards,

Hello @darla14 

It may be due to the fact that there is no settings can or should be configured throw the STM32CubeMX for this peripheral (like bauderate for usart or other parameters). So, there is no configuration space and the warning is just to indicate this. For the GPIOs used for the CSI, you should be able to see them on the graphic of the MCU or on the GPIO Tab (same for pins used for other MCUs).

Best Regards.

thi is what I see on GPIO TAB ( only i2C which I have enabled) . On
the graphics yes they are chosen but in red.

Hello @darla14 

This is a known behavior that has been reported before (under internal ticket number 215638). It should be solved ASAP.

Best Regards.

Hello @STTwo-32 ,

Thanks for the response and confirming this.

what will be the actual output of the ticket? Able to see the corresponding gpios related to CSI? May i know does the pin number will vary among the other variants of the STM32N6? Like between X,B and L version? 
regards,

This ticket will ensure you see the CSI pins in green once this peripheral is enabled. For the Variant MCUs. This is not the main topic of this ticket. If you want to have an answer or escalate an issue on it, please create a topic for this question since it is not related to the original topic of this issue.

Best Regards.

Hello

I'm also facing the same issue as you at the moment. Could you tell me if your problem has been solved? And could you please explain the handling method?

This can definitely be confusing, especially since peripherals like I2C and SPI clearly show their GPIOs in CubeMX, but CSI doesn’t.

For the STM32N657 series, the CSI interface works a bit differently. Its pins don’t always appear in the “Flip” section because they’re tied to a dedicated hardware block with fixed or semi-fixed pin mappings. In many cases, CubeMX only shows them in the main Pinout & Configuration view once the peripheral clock is enabled, so it’s worth double-checking the RCC settings too. The “no parameters to configure” warning is normal for CSI on this device.
