Split from this thread.Hi there, switching to USART3 didn't work. I still don't see any messages in the serial console. the second time I try to connect to the serial console gives this error.
USB-PD MCU for Display Port Source - Power Sink
Hi, we are developing a device which outputs display port over type-c and needs to sink power. Similar to Laptops when connected to hubs. The required power is less than 60W. Im looking a for a suitable USB-PD implementation for this purpose. Can thi...
Resolved! Is the USB Audio sample missing a PMA address configuration?
Hi all,After reading through both the HAL, low-layer and USB Device library code flow several times I am still confused about a peculiar point.When I ask STM32CubeIDE to generate a Custom HID base implementation, I get a "usbd_conf.c" file that has a...
Only 16K of 8M PSRAM accessible on B-U585I-IOT02A
I'm using a B-U585I-IOT02A board and the IOT_HTTP_WebServer example code. My read is the PSRAM is 8M on that board, but I can only access 16K (to 0x2803ffff) and then ???? is not IDE memory display or a trap in the code. Is this a CPU configuration ...
STM32G474 On-the-Fly Flash Update: Handling ramfunc and CCMRAM Functions
Currently, on the STM32G474, I am able to perform on-the-fly flash operations and interrupt vector relocation using BF_MODE and VTOR. However, I have encountered an issue: when a function is placed in RAM using the ramfunc attribute or located in CCM...
IS66WVO32M8 OSPI problems
Hi All!I try to use 2 pieces of IS66WVO32M8 PSRAM with multiplexed OSPI ( only the NSS pins not shared ) with STM32F585 in memory mapped mode.Previously, I used 2 pieces of APMemory's APS12808L in memory mapped mode without any issues.I reconfigured ...
