Hi folks,I have SDMMC1 working on CM7 on my H755 Nucleo. Now I want to migrate FAT-FS and the uSD to CM4, in which case I think I should switch to the SDMMC2 peripheral since it's in D2 domain along with CM4.I have a some questions about this and wou...
I am laying out a USB for a STM32H725. I would like clarification on something out of the datasheet (DS13311).Note 2 under table 118 states: No external termination series resistors are required on USB_DP (D+) and USB_DM(D-); the matching impedance i...
I have several problems with the NUCLEO-H7S3L8 board 1) When initializing the USB - HS peripherals, I getting stuck in the "USB_CoreReset" function: Related problem and after some time when (count > HAL_USB_TIMEOUT) the program goes to Error_Han...
I am using an STM32U585QI. I have some memory mapped PSRAM that I'm using. I have enabled DCACHE, but do I have to manually do something with the MPU for it to cache memory accesses to/from the memory? The reference manual says:"In addition, the A...
HelloI am using STM32F103C8 and I want to read and write to CAT28F010P Flash chip.This flash chip has parallel buses for data and address. Also there are 3 control lines as CE, OE and WE.So there are 28 lines in total coming out of this chip. I was a...
Hi, I find the search system on the ST website to be lacking. There are a lot of parameters I can't search for/filter by. Is there an ST e-mail / form contact I can use to ask for help? If anyone here can help, I'll try to describe what I am looking ...
Hello,while using this mcu 16bit adc a strange thing happens.the adc signal is test under a sinusoid signal(0.5Hz from a signal generator), and as shown in the figure at certain level adc keeps unchanged, after leaving this level then the signal incr...
Hello there!I've designed a board based on the STM32H743Zit Nucleo board, but unfortunately, I'm facing difficulties with the USB functionality. I'm unsure if it's a matter of configuration or firmware. When I tested USB settings and functionality us...
Hello there! Esteemed ST team member,I hope this message finds you well. I'm reaching out to address an issue I've encountered.I've designed a board based on the STM32H743 Nucleo board, but unfortunately, I'm facing difficulties with the USB function...
Hello, I designed a similar board using STM32H743ZIT6 and STM32H743VIT6. (Rev. V)The board works fine normally.It has been in production for 3 years already. Boards that have already been produced and shipped sometimes become unusable. (since a few m...
