LPC4088DM Things to Note
These are the things to take note of regarding the display modules:
- The current implementation of the USB Host stack is rather slow. It reaches about 82Kb/s read speeds and 65Kb/s write speeds. The uSD card is about 15 to 20 times faster. Read more about it on the Performance page.
- Copying data between the uSD card and the QSPI flash is not working, likely due to a DMA issue. A workaround is to copy to a buffer in external SDRAM first. This workaround is used in the benchmarking program.
