Using SWD pins as GPIO

2024-11-19
Hi,at the moment on the STM32U5G9 we have the SWD pins (SWDIO and SWCLK) set to DEBUG, but we would like to also use them as GPIO after programming. Are they always set to SWD for programming and then revert to GPIO automatically after programming or...

GPIO_Analog pin without ADC connection?

2024-11-17
Hi,on the STM32U5G9VJT6Q, when I click on many pins such as PD5 (screenshot below) it shows GPIO_Analog but there does not seem to be any ADC channels (or other analog functionalities) connected to it.What does setting it to GPIO_Analog do?Can I stil...

TIM8_CH3N seems to be output on the incorrect pin in CubeMX

2024-11-17
Hi,on the STM32U5G9VJT6Q, according to the documentation and also to the Pin export from CubeMX including the Alt-Functions, PH15 should be able to be set to TIM8_CH3N.But in CubeMX (see screenshot below) when I select Channel 3 PWM output it sets it...

QSPI mapping of pins IO4 - IO7 to the normal 4 data lines (D0..D3) of QSPI NOR FLASH

2024-11-17
Hi,I configured the STM32U5G9VJT6Q to use QSPI to interface to a NOR FLASH ( MT25QL128ABA1EW9-0SIT ).Because of other connectivity, the only option for the data lines (Data [3..0] as highlighted in yellow in the attached screenshot) is "Port 2 IO [7....

Resistor for SWO pin isolation from SDMMC data line on STM32U5G9

2024-11-15
Hi,I would like to enable the SWO signal on the SWD connector, but one of the SDMMC data pins is already using that line. To avoid creating a long stub on the SDMMC bus leading to the SWD connector—which could cause line reflection issues due to the ...
