    Just had a chance to try this. First I updated to latest set MTP_Teensy changes then update usb_mtp.h and usb_mtp.c from your cores branch.

    Ran the example_2_simple_t41_qspi sketch and MTP...

    Good Morning Matt welcome to your first post.

    As to your question. If you look at section 56.2.3.3 of the 1160 Reference Manual for the 1160 you find:

    Basically when you read the UPOS...

    May not be popular but I would say punt. The JPEG and PNG libraries are already now standard libraries.

    That probably the best approach. Be curious what you come up with. Never seem to be able to tie all these projects together - keep getting distracted :)

    Nice work and yes think MTP+Serial would be a good idea - a lot of other USB types have this type of setup as well so would be right in line.

    I ran Defragster's huge file sets writing them directly to the N02 NAND Flash.

    Don't think so - I usually do a format (quickFormat) from explorer prior to starting a new series of tests. LFS filename length has been set to 39 for a while. I am attaching a zip of one of the...

    Just downloaded the cache branched and seems to be fixed and working. File sizes are correct, images display correctly and mp3's play to completion without a problem

    As to your first point I agree with you, writing 1000 small files is not expected usage pattern for flash chips. There were a couple of reasons was looking at erase size again: (1) trying to...

    Nice job. My preference is just to write the values:
    221,120
    234,123
    etc,,,

    Your first line in the file could always be
    x, y
    just for reference

    Thank you for the detailed explanation on the NAND timings. It really helps for the future. To be honest forget all about the max value for SPI for the IMXRT1062. We have been running SPI at all...

    Thanks for checking Tim but we may have to reduce the 45Mhz to 30Mhz. Have to run some more tests

    Tim try changing the SPI clock from 55Mhz to 45Mhz in littleFS_NAND.cpp - think that change works for the TMM but don't understand why have to slow the speed down for the TMM?

    Thanks Paul - while my soldering has gotten better feel better if its not too much trouble if you can solder if you have an extra board. If not I have an extra board I can use.

    I just checked Mouser and Digikey, both are out of stock on the W25N02KVZEIR NAND. So can not even get one so I can compare apples to apples. But in lieu of the N02 I used a M02 NAND 2Gbit Flash...

    Hi Paul - didn't realize about NOR 2Gbit Flash and 4Gbit QSPI NAND chips - we have always been working the Memory Board with has the W25N01GVZEIG and the W25N02KVZEIR so hence the shorthand.
