SDIO fail to run over freq > 2MHz
Hello Everyone !I am using 4bit SDIO over STM32 F4 Nucleo board (STM32F412ZG).I am facing issue when running higher SDIO_CK clock.When I use smaller 'Div' value (higher freq), it does not produce correct clock and in stead produces very small clock i...
Resolved! CubeMX / STM32L476 / NAND Flash
I'm trying to experiment with a NAND flash connected to a STM32L476VG and I'm using CubeMX to set everything up. No matter what I do, I cannot get CubeMX to show me a NAND flash as an option for the FMC. The options are LCD, Muxed NOR and Muxed PSRAM...
