Hi everyone,I’m working with an STM32H7S3 microcontroller and an external Octo-SPI NOR flash IS25WX064 from ISSI (datasheet: https://www.issi.com/WW/pdf/25LX-WX032-064.pdf)My goal is to get this memory working with ExtMemLoader (including XIP support...
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, I am using an STM32H755XIH6 MCU in a custom design. I want to use only LDO supply configuration for the internal power regulator that provides the VCORE and I don't really intend to use the SMPS configuration. My schematic has some hardware mista...
So i'm following along with this video* https://www.youtube.com/watch?v=usQ_f6Swpok&list=PLTJzs51NlEICI7ARAHOyUqMhTgJE0UFv0&index=5 I have the same* STM32N6-DK board This is my build command for the GPIO_IO_Toggle application.* /opt/st/stm32cubeide_1...
Hello ST Experts,I am using an STM32H755ZIT6 with W25Q256JV flash in Quad-SPI mode at 100 MHz.On our latest hardware revision, we observe occasional QSPI read failures and flash communication instability.During analysis we found:1. QSPI signal oversh...
Hello, Can I say that "IDLE" is equivalent to "RTO with 8-10 bits (depending on framing)"?Or are there some other subtle differences? My goal is to transfer received data with DMA and start interpretation of the data when nothing is received on the l...
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 wh...
Hello,let say that STM32H753 mCU has connected VBUS (via resistor divider to be sure that voltage on VBUS detection pin (PA9) would never exceed AMR), D-, D+ and GND lines with PC, before mCU core is supplied. At the moment when mCU core is then conn...
Hello,I’m working with an STM32N6570-DK, and I’m trying to run a very simple LED-blinking application as part of the FSBL.When I debug the project using STM32CubeIDE, everything works correctly and the LED blinks as expected.Next, I want to flash the...
Hello! I'm now using a STM32F469 to drive a screen with MIPI-DSI Interface. I need to send the initial codes with low power command transmission, and then drive the screen in video mode. I think LPDT it is supported by this MCU, but I'm not sure how ...
