Hi,I am currently working on the firmware of a PCB with an STM32G031K8T6 as the MCU, supplied by a 1.8V voltage.When I enter Stop 1 mode, the consumption of the MCU drops to 100uA, instead of the 7uA stated in the datasheet.The app_stop function is a...
I am designing a system that will utilize the dual bank feature of the STM32 devices to make a robust system for OTA updates. I am currently using a STM32U545 for my project and have questions about writing to the FLASH_OPTR to change the SWAP_BANK b...
Hello, I'm posting a new message because the previous one was not answered with successful connection. The problem is that when MCU is populated on my board with Read-Our Protection enabled, it is not possible to connect STM32CubeProgrammer v.2.21.0 ...
Hi,I'm using OCTOSPI in Mode Quad SPI on a STM32H563ZIT6. I'm having issues when reading Serial Flash data with a 1-1-4 (6Bh) read, 1-1-4 (32h) write is working fine. Also 1-1-1 read and 1-1-2 read also work fine. The serial flash is IS25LP032D. I...
In the lower-end STM32L4, covered by RM0394, SRAM is partitioned into two parts, SRAM1 and SRAM2.SRAM2 (besides being "special" in that it has ECC and automatic erase facities), is mapped at both 0x1000'0000 and at the end of SRAM1 in the 0x200x'xxxx...
Hi, everyoneI recently encountered a strange phenomenon. I opened three DMA channels on the STM32G474RBT6.The first one is Channel 1 of DMA1 (circular mode), which is used for automatically collecting the data converted by ADC.The second one is chann...
Been reading thru the F103 datasheet to try and figure out why my TinyUSB based code isn't working. The datasheet says.. "For mono-directional/single-buffer endpoints, a single register can be used to implement two distinct endpoints". The F103 has...
Hello, We are facing an intermittent CAN-FD issue in the field and would appreciate guidance from the community. Our system has two devices on the bus (no other device on the bus) using a request–response architecture. The master sends a request ever...
I have a situation where a USB endpoint stops working due to a control packet being NAKed in the handshake phase. I've traced the problem down to the STM USB stack setting DCTL.SGONAK = 1 in response to an INCOMPISOOUT event, yet in the case when it ...
Hi everyone,I am using a STM32H563RG and I need the RTC to work even if the VDD is powered off. To do that, I am plugging a battery on the VBAT pin to power the RTC and the Backup domain. But I tested it and it seems the RTC is stopped and the backup...
