Hello everyone. I am trying to write a bootloader with STM32H750IBT6 and mt25ql512. I am trying to adapt the ExtMem_Boot example of STM32H750-DK to STM32H750IBT6 by modifying it, but I can't succeed. It doesn't make sense why STM32H750IBT6 does not w...
Hey guys, I'm looking for some suitable HexaSPI PSRAM and also the OctoSPI Flash for the STM32N645 board I am just building.. I cant find the parts used on the DK so do you have a list of supported memories? I need 256Mb PSRAM and will start with a 1...
Hello, I am planning to use the STM32G474RET6 and would like to confirm whether I can use the internal VREFBUF. This product's package is LQFP-64 and while reading the datasheet I noticed the note : ''The VREF+ pin is double-bonded with VDDA on some ...
Hello,The datasheet and reference manual are missing information about the 4 KB Backup SRAM in the memory map.Where can I find details about it?We need to use this memory in both Secure and Non-Secure projects.Thank you.
Hi,The external nor flash AT25XE321D is 32Mbits, support quad IO/XIP spi operation, max. 133MHz Freq. Std. JEDEC/SFDP. It is connected to STM32H7R7Z8J6 with with XSPI1 port-1 interface.I am using MX v6.116.1 to setup project for my board. By IDE v2.0...
Dear allI am using STM32H563 and interface with some CAN bus sensors to receive and sometimes send data to them. The CAN bus sensors are developed by a partner company. I developed my software refer to FDCAN_Com_IT example provided in IDE firmware pa...
Environment: STM32L4 + 32.768K LSEFunction: Wake up and work once every hour, then enter stop2 mode. During the one-hour sleep, wake up every ten minutes to feed the external watchdog.Problem: The device resets directly when waking up every ten minut...
I designed a PCB using the STM32H743 in the TFBGA240 +25 package.When I power the board, the STM32 gets hot. I measured the voltage across the VCAP capacitors, and it is 2.2 V, while it should be a maximum of 1.35 V.What could be causing the VCAP vol...
In rm0316 rev 10 for the stm32F303x, the documentation for the ABRQ bits in the CAN_TSR transmit status register states: Setting this bit has no effect when the mailbox is not pending for transmission. I am finding on my STM32F303 that setting ABRQx ...
Hello, I was writing some code and one day a handler_reset() appears in the debug panel It is said that appears because it give the opportunity to the user to debug from the very begining. But why? if there is already the ability to set the breakpoin...
