Resolved! Problems submitting questions to this board
This is just a test. Has anybody else been unable to submit questions? I keep getting a red error message.

How long does the NRST pin has to be held low to trigger a reset (STM32F103RC) ?
In my design, I have two MCUs, the STM32F103RCT6 and an ESP32. At some point, the ESP32 will perform a firmware update of the STM32. So it will need to reset it through the NRST pin, controlled through a GPIO. I have checked rapidly the datasheet, th...
Resolved! How to solve the problem with: 1. " Error: No STM32 target found!". 2. "Error in final launch sequence: Failed to start GDB server Failed to start GDB server Error in initializing ST-LINK device. Reason: (4) No device found on target."
--The first error encounters while trying to connect the board (STM32H7A3ZI-Q) with STM32Cube Programmer at normal mode.--The second error encounters while trying to upload a code through STM32Cube IDE. However, when I try to connect the boa...
Bank Swap
There is a point that confuses me, I am reading from the datasheet, but I wanted to ask some questions.For stm32f4, there is FB_MODE bit in the SYSCFG register (8th bit), if the FB_MODE bit is 0, the address 0x08000000 becomes BANK1, if it is 1, the ...
STM32H7A3/7B3 operating frequency
Why the operating frequency of ATM32H7A3/7B3 is limited to 280 whereas the other families in H7 series supports minimum of 480MHz
How to use External Loader to load initialised data into NOR Flash on Octo-SPI interface on STM32L552E-EV
Hi all,I'm working on an STM32L552E-EV and trying to declare some constant data into the NOR Flash connected on the Octo-SPI interface. I want to have the Octo-SPI in memory-mapped, so that the constant arrays can be accessed easily in my code. To in...
Octo-SPI memory-mapped mode speed for H735
Hi,We are using the OCTOSPI2 on a H735 in memory map mode.We are copying 32 bits values one by one, from the internal RAM to the Octo memory.We transfer around 5000 x 32 bits in 2ms which is around 10MB/s.I think, it is a bit slow. What is the maximu...
Resolved! Using OCTOSPI in Memory Mapped mode with an QuadSPI SRAM
Hi guys,I am using an STM32L552ZET6 and I would like to extend the RAM using an external SRAM chip (23A1024-E/TS), that has an QuadSPI interface. I would like to know if I can use STM32L5 OCTOSPI interface in memory mapped mode with the above mention...
STM32F103 upper flash pages corrupted/erased.
Dear ST community,I was wondering if you could help me with a problem I'm having with an STM32. I have a system containing an STM32F103VET6. The last flash pages are used to store settings/parameters. 2 redundant flash pages are used. This system...
Switching Port Pins between Alt Function and Normal mode
Hi All,In a situation where someone might be flashing an LED using a Timer Output (eg Alternate Function Mode connected to a Timer channel output), what if you want to then turn the LED on solid or totally off and then maybe back to the Timer flashin...
