NUCLEO-H743ZI2 bootloader Issue

Hi,I have shorted BOOT0 pin to Vdd of Nucl0-H743ZI2 and wanted to issue bootloader commands over I2C bus(PF0 & PF1 are used).I am observing RED led to be turned ON as soon as bootloader is loaded and i am not getting ACK from H743 . But if bootloader...

Using f_write in a loop to write multiple chunks of data, doesn't seem to work

I'm using the following code: //100KB buffer uint8_t testBuffer[100000];   for(int i = 0; i < 100000; i++) { //Fill buffer testBuffer[i] = 'U'; }   BSP_LED_On(LED_BLUE);   for(int z = 0; z < 5; z...

I've downloaded a patch to STM32Cube_FW_L0_V1.11.0. Now that it's downloaded, what should I do with it?

Firstly, I downloaded STM32Cube_FW_L0_V1.11.0 and, following the instructions in the documentation that came with it, extracted it to a folder. I presume that this is all I need to do to enable using within STM32CubeIDE - simply navigate from the ID...

Does ST ever program system memory with a customer's boot-loader? If yes, who would I approach or how would I go about it?

Slow download via LwIP

Hi,I'm using STM32H753 and STM32F746 for downloading around 13MBytes.I'm using LwIP library.I get download rate about 1MByte per 1 minute.Is it make sense to download so slowly?when I check with speed test on the same network the download rate is 110...

STM32F446 SVD file lacking PLLR field of PLLCFGR

According to the reference manual (RM0390) main PLL in F446 has a third output, defined by PLLR, where previous version (F429 et al.) had reserved bits (with same reset state). But in latest (1.2) revision of F446 SVD file that field is missing, and ...

The SVD files with <enumeratedValues>

We are trying to provide safety with Registers . I downloaded the svd files for TI and ST, and the STM files (for example for STM32F411 micro) does not have any <enumeratedValues>. The SVDConv.exe says something like this:Area of improvements: * De...
