Resolved! SPI mode and UHS-II mode not supported for STM32U5xx
Hello,I have a very basic question. In the spec of the U5 series there is this: Does that really mean that the U5 would not support talking to an SD card in SPI mode? I find it hard to believe since SPI seems to be the most basic way to interface wi...

Resolved! STM32H750 FMC + LCD
I’m having some trouble related to using the FMC to interface with a LCD. We are using NE1 as chip select, LCD register select is A0, 16 bits of data. When I’m scoping the signals, I’m seeing the A0 go high during 16 bit writes to 0x60000000 (comman...
Resolved! AES v SAES
Hello,The STM32U585 Reference Manual say these chips have one AES and one SAES peripheral. In turn each of these have an "AES core algorithm (AEA)" component. I expect that to mean that there are two physically independent AEA's on the chip. Is that ...
Resolved! I2C Slave hanging after 30-45 minutes of correct operation
Hi,I have a STM32F103C8T6 configured to operate as an I2C slave device on I2C1. It operates as intended for 30-45 minutes before the I2C hangs indefinitely with a HAL I2C state code of 0x2A = HAL_I2C_STATE_BUSY_RX_LISTEN. In this state, further I2C t...
