I am trying to implement a USB 2.0 FS device on STM32H5 without using HAL or anything else. There might be a need to send back a request error (STALL) during enumeration:- and it is OK to return STALL to an IN transaction, so I can set STTX to STALL ...
It's my understanding that it is a bad idea to mix lead-free and leaded solder, and that it can cause cracks.I'm using a TFBGA100 package on an STM32H7 and have some long-term reliability requirements. In order to avoid tin-whiskers, I was considerin...
I read RCC RSR to determine the cause of reset. It is not clear to me the purpose of RMVF bit. I guess it resets the other flags but why would I want that ? I wonder if I am missing something.
What is the maximum clock source frequency can I use as an external clock for timer?I have a 20MHz source and PLL frequency made out of this source. The purpose - generate lower frequency pulses that synchronous to that 20MHz clock with controlled de...
Ok, 2 part question. The UART bootloader defined the "special" and "extended special" commands. Those are nicely integrated into OpenBL. So if I wanted to write my own custom "OpCode", what range would I use ? Looks like some are used for STM32WB (FU...
Hi,I'm using STM32H563 and managed to set FLASH_EDATA1R_CUR as needed (EDATA1_EN="1", EDATA1_STRT="111"). Then I tried to read 64-Bit at once from Address 0x09000000. Unfortunately I get a hard fault. Is it intended to read more than 16 bit from the ...
The STM32H573I-DK is now available for order! It is the first kit to support Secure Manager, a turnkey system-on-chip that integrates core security services certified and maintained by ST. The STM32H573I-DK enables developers to explore all the integ...
I have VREFBUF configured for output to comparator on my board. I see this on MCU Vref+ pin...Is 1.2MHz waveform typical? Are capacitors on Vref+ expected to smooth? I looked for avg closer to 2.5v (VREFBUF_VOLTAGE_SCALE0). How close to 2.5v should t...
So the startup code first sets the stack pointer, and then jumps to SystemInit for early initialization, then copies the initial values of data and zeroes bss region and then kickstarts C startup. Is there anything hardware related that has to be don...
Hello,I am using the Cube Code Generator, within the STM32CubeIDE (version 1.13.1) for an STM32H563, and have configured the Flash Data Sectors to use the maximum 8 sectors per bank for EDATA. The valid range for the EDATA sector size is 0 - 7, as sh...
