Hi
I finaly got my EMMC/SD Card project running. I can read write to my EMMC with ~30 MB/s on a stm32F4.
At the moment my USB is too slow. In the forum I read that first thing to do is to multiply MSC_MEDIA_PACKET by 2,4,8, ....
THe problem is that as soon as I change the Value of MSC_MEDIA_PACKET windows no longer recognises the USB MSC. I used value MSC_MEDIA_PACKET = 256, 1024, 2048
Non worked. I also increased the size of heap and stack. No success.
Any idea why windows doesnt recognise my USB device with MSC_MEDIA_PACKET other that 512?

Make sure the read/write functionality handles multi-sector operation, validate / instrument
