WebFeb 21, 2024 · There are a few ways to make QSPI writes work faster, i.e. erase in larger sector size (64kb insead of 4kb that is implemented in current libDaisy code), use DMA for writing large blocks of data (to avoid polling). I imagine some of it can be done when there would be official flash writer solution for libDaisy. WebUSB Interface Design Guidelines 4.5.3. QSPI Flash Interface Design Guidelines GUIDELINE: Ensure that the QSPI_SS signals are used in numerical order. GUIDELINE: If your design uses QSPI flash with 4-byte addressing, design the board to ensure that the QSPI flash is reset or power-cycled whenever the HPS is reset. 4.5.4. picrew toddler
