Windows format request failing on Mass Storage Example on 11U14 and 0.98a

Hi guys,

I have Mass Storage reading my SPI flash no problem, however when I attempt to format in FAT, the first 512B packet (1st sector) sent by Windows is not what's received on the other end by the SCSI driver:

------------------

Endpoint_Read_Stream_LE(buffer,VIRTUAL_MEMORY_BLOCK_SIZE,NULL); // Line ~322 SCSI.c - does not return expected packet

------------------

I have confirmed that the correct packet is being sent by Windows, in the entire transaction before Windows decides the format has failed, only a single 512B outgoing packet is sent and this contains a valid FAT header.

On the receiving end, however, the data that is retrieved does not match this and appears to contain data from the descriptor, I'm wondering if there's some buffer overflow/crossover here or if we're somehow looking at the wrong place in memory?

Many thanks for any help

This line of code is #ifdef'd out (#if 0) in the v0.98 release. Did you change this?

Yes I did, I'm using SPI flash with sector writes, endpoint streaming seemed optimised for direct memory addressing?

I just want to confirm I have the same issue. Format always fails after the first sector written.

Did you ever found a solution?

I've been on hold busy with other things so nothing yet, would be great to hear back from NXP about this one.
