Compatibility Issue | Description | Impact | Workaround / Notes |
|---|---|---|---|
Lack of HAL support for extended CSD register | HAL only reads CSD, not EXTCSD, leading to incomplete device info | Incorrect capacity reporting, limited memory | Manually read EXTCSD register for correct device info |
Incorrect addressing mode assumptions | HAL assumes byte addressing for devices <2GB, but eMMC uses block addressing | Capacity read as 1GB instead of actual size | Use block addressing mode; stop HAL converting to byte addressing |
RX FIFO overrun errors during data reads | Slow or unoptimized code reading FIFO causes RX overrun errors | Data transfer failures, especially in debug builds | Optimize FIFO read loops; build with optimizations (-O3) |
Performance and data transfer issues | Debug builds with gcc are slower, causing timing issues | RX overruns and data read errors | Use optimized builds or adjust code to speed up FIFO reads |
Platform-specific reports | Issues documented on STM32F4, STM32F7, STM32L4 platforms | Compatibility challenges with these MCUs | Workarounds tested and confirmed on these platforms |
Tip: Engineers should always check platform guides and test emmc storage to avoid these problems.
