Hi, Having some grief getting USB MSD device to work, following some notes from Alan C. Assis from around 5 years ago.
It is an MT25Q 32Mbyte spi nor flash device, registered as /dev/mtdblock0 and also mounted and initialised as an nxfss file system at /mnt/flash. I can read/write to it from nsh. If I run MSCONN, it crashes: nsh> msconn mcsonn_main: Creating block drivers find_blockdriver: pathname="/dev/mtdblock0" ftl_geometry: Entry ftl_geometry: available: true mediachanged: false writeenabled: true ftl_geometry: nsectors: 131072 sectorsize: 256 usbmsc_exportluns: Starting SCSI worker thread arm_dataabort: Data abort. PC: 2002f528 DFAR: e8bd8800 DFSR: 00000005 up_assert: Assertion failed at file:armv7-a/arm_dataabort.c line: 160 task: msco It seems to be somewhere in task_init and group_setuptaskfiles (duplicating files I think), but debugging deep inside NuttX is, um, scary! I'm hoping I've just not configured something else it needs; and I can't seem to find any relevant debug options to assist - USB MSC MM DEBUG seems to cause it all to hang up at a printf statement in the msconn app. Any thoughts, kind people? Thanks, Tim.
