Hi,We are currently using an stm32l5 in our product and experimenting with a stm32L562E-dk and with the official TFM (https://git.trustedfirmware.org/TF-M/trusted-firmware-m.git master branch on the latest commit at this date.) The TFM is unmodified...

Hi,We are currently using the STM32MP1 DK2 board for our project.We have to use FreeRTOS + UART7 and USART3 with DMA Our issue arise when FreeRTOS is used with an UART (USART3 or UART7 in our case) which use the DMA.We have reduced the project to the...

Hello Remy,Thank you for your answer,Is this a STM32WB special requirement ? I haven't seen in the Bluetooth SIG specification the fact that no services present should lead to a disconnection.Regards,Romain

Hi Jhoud,Yes I have considered the banking of the SCB register when in executing in S or NS application.I have already played with the STM32CubeL5 introduction package but now we want to be on the latest TFM release and unfortunately, on the stm32L5 ...

Hi @JHOUD ,Thank you for your quick answer (and sorry for my delay, Christmas holydays have come and gone !).The RDP Level is 0 (0xAA) (this is the one configured by default on the TFM ST implementation), value confirmed after reading RDP value usin...

Hi,Thank you for your answers, it's more clear now.I don't have issues anymore with the step vs stepi neither with breakpoints. I was playing a little with the gdb environment at that time, maybe I deleted some important lines at that time.Thank you ...

Hi Olivier,Thank you for your answer.We have already tried to extend the stack size. This doesn't change the behavior of the program.You will find attached one of the .ioc which trigger our issue.Regards,Romain
