Resolved! Marking on part STM32L151R8H6A mismatch with data sheet
Marking on actual part STM32L151R8H6A is “151R8H6A�? but data sheet is “L151R8H6A�?
UART/USART DMA IDLE Receive with unknow data
Hi,I'm trying to build a software to retrieve data from an solar inverter.After I success to send data, it was the time to receive the data. I choose the method with DMA IDLE to receive data in a circular buffer.In this mode, after a lot of debugging...
Byte is lost from UART packet after being put into memory (DMA)
We have run into a problem where a new run of boards with STM32F429ZIT MCU's have been losing a byte (always loses a single byte which seems odd) from the UART communications that are sent to DMA.We send packets of UART data to the MCU and the data i...
Resolved! STM32F777 new revision 1
I've bought some new STM32F777BIT devices with datecode 145 marked with a new revision code 1.All my older STM32F777 was marked with revision Z and current errata sheet ES0334 Rev 7 mentions only revisions A and Z.What are the differences between rev...
What can cause a STM32F407 to fail to execute the firmware at 0x08010000, but execute the bootloader at 0x08000000, even if I have completely re flased both of them with a ST-LINK. It works on all the boards, except 2 of them. same board revision. !!!!!!
The only part I am not familiar with is all the registers, is there something that may have been corrupted, and I should set back to some values ???
TIM15 can't be enabled when OPM bit is set, why?
Hi everyone,I am having issues getting One Shot Mode enable when using the TIM15. I am currently using the STM32H743ZI as the MCU.When setting the OPM bit in the TIM15_CR1 register the CEN bit in same register no longer can be enabled for whatever re...
Resolved! How to connect 3-4SEL to SPI2_CLK on STWINKT1B Eval Board?
Hi,I would like to have SPI2_CLK signal available on the CN2 connector (STMod+ interface) on the STWINKT1B eval board. Based on the schematic, looks like one can activate SPI2_CLK signal on STMOD4 via the 3-4SEL pin on the STG3692 digital switch. But...
Resolved! for the STM32l412 MCU - Is it possible to get LPUART interrupt while write & erase page on the internal NVM flash?
when performed NVM operations (write on page and erase page), i lost some recieved bytes in my LPUART Rx line.when i uncomment the part of writing on the nvm, the lpuart works fine.can any one please tell me if there is a way to use this modules toge...
