RASPBERRY PI PICO DEVICE MSC INCREASE SIZE

gabofienco
Hello all,
I am working in a project where I plan to use rp2040 tiny usb device to store some files greater than 5MB in a SDCARD.
My question is.. any ideas how to make the MSC device to point to the address or path generate by rp2040 to the SDCARD??. and if not possible to change the pointing address will be good to know too.
Or how to make the device MSC to look with a size of 128MB in windows just like it does when it is in boot mode?
I had used these references, but I still can't have a good mounted device with a bigger size that is not overflowing flash/ram.
Thanks for your time.

    Does the Pico consume the data at a high data rate? If not, why does the entire file need to be transferred; can't streaming provide a solution, if this device is permanently tethered via USB to some device that is not in a reachable position?

    A bit more information is needed, because this seems badly architected.

    Yes it does, I am really sorry that I can't give more details about the application, I am not allow to.

    And I really appreciate the possible hardware/design updates you guys could give me, but my question is only focus to firmware. hardware is what it is!

    I already manage to update the msc size playing with the byte per sector, sector per cluster, etc etc in the middleware, I am trying to solve another thing when I copy files larger than 1MB now.

    Thanks everyone for your answers.
