Hi,

    The description of the STM32L152D-EVAL Evaluation board said it support ''2 GByte (or more) MicroSD Card on SDIO''. I want to make sure wether it support MicroSD more than 16GB. Since there are some differences between SD cards below and exceed 2GByte.     This is very important for my project, thanks! Regards. #stm32l1-microsd-sdio

Hi meng.cheng.001

 Based on the product reference manual the SDIO peripheral is fully compliant with SD Memory Card Specifications Version 2.0 so it can reach up to 2 Terra (2^32 * 512 bytes block size).-Syrine-

I've tested STM32 SDIO hardware with MicroSD cards of sizes 64GB and 128GB

You'll have to ensure your drivers/software are suitably coded for SDHC/SDXC cards, but the hardware is workable.
