Resolved! Power on reset (PORRST) not detected on STM32L471RGT6
Hi, I am trying to detect whether a reset event was caused by power on rather than any other reset such as a button reset or a software reset. I attempted to use if (__HAL_RCC_GET_FLAG(RCC_FLAG_PORRST) != RESET)but the compiler reports that PORRST ...
Resolved! Do the G4 series contain a DMA on timer break feature?
The RM0440 ch. 28.3.18 rev7 mentions on page 1128:> An interrupt is generated if the BIE bit in the TIMx_DIER register is set. A DMA request can be sent if the BDE bit in the TIMx_DIER register is set.Unfortunately, the DIER register does not contain...
DCMI and PSSI HAL DMA routines are not using half complete callbacks, but it is possible.
Hello. I've noticed that DCMI/PSSI code does not provide this functionality, but it is very handy when using DMA in circular mode (ADC, frame buffer pumping to other interfaces, etc.). I've tested DCMI+DMA circular mode on F4 and PSSI+DMA circular mo...
Where single stepping with STM32H7 code works?
Some ARM/STM32H7 CPUs have a problem with single stepping through code. Which CPUs didn't have this problem? I have planned to use STM32H750 because it is now somewhat available, but I could swap.
I have designed a custom stm32f407vgt6 board with on board stlink, similar to stm32discovery board. But the st-link after assembling, the st link is not being detected by any application. Please let me know how to solve the issue.
I have tested all 3v connections going into the st-link chip, but the bi-color led is not blinking when it is connected via USB. Please help.

Hi, I'm trying to do embedded 103c8t6, and I'm having some trouble with selecting the right crystal.Here is my Schematic. I'm using ABS07-32.768khz with 12.5pF load Capacitances and the equivalent series resistance is 70kR. I took Cstray as 5pF that'...
Resolved! Older STM32H743ZI MCU Nucleo board was updated to V3.J10.M1 firmware version. While The board can be flashed, it isn't possible to debug or erase chip memory. Is there a way to roll back the update?
After running into some issues during an OS migration, I ran a firmware update on a nucelo_h743zi board using the stLink utility. After this I ran into many issues with flashing and debugging. While I can flash the board with openocd v11, it has some...
