I solved it :D haha. It was only about settings as I thought. Problem with merge example USB Device and SD_MMC caused this
/* Enable ICache and DCache */
1) Merge example SD_MMC_EXAMPLE and USB_DEVICE_EXAMPLE (virtual memory is mapped instead SD card) from ASF
2) Remove #define CONF_BOARD_ENABLE_CACHE
3) Set LUN_0 to DISABLED and LUN_2 to ENABLED
4) Remove VIRTUAL_MEMORY_ENABLED from Symbols in project settings
hello I have the same problem and i'm using same70Q21 processor
I can't find these 2 examples that you said I should merge at step 1
I found SD_MMC but 2 examples 1 for fatfs and raw access
also how do I merge 2 examples?
Can you help me with this ?
