small SD card

[Jobd0ne]

A bit of a weird one this , and one most people will likely not have an issue with. I recently changed the sdcard from an old 4GB I had to an even smaller 64MB as I thought it'd be a waste of space with the 4GB. I had no issues with 0.4 firmware, but when upgrading to 0.5 (using the build from the site on a pico (not a pico2) the card can no longer be read. if I replace the 4GB back in, it works fine.If I flash 0.4 back, it reads again.

G'day. These issues are obviously hard to reproduce without the specific SDCard. What I've done is updated my fork of the SDCard library to the latest revision and produced a new pre-release 0.6 build:

Please try it out and let me know how it goes.

I can confirm that 0.6a still doesn't work on the (super) small SD card. just for kicks I went back to 0.4 and of course it worked. I wonder if you built 0.4 again , it too would fail? Of course the obvious solution is just to change the sdcard :).
if it's any help, here is a link to the card https://www.aliexpress.com/item/1005007118463161.html

Thanks for trying it. Significant changes were made (by the author) to that library between my 0.4 and 0.5 PICO-56 builds to support the Pico 2 and newer Pico SDK. Likely something intentional or othwrwise in those changes broke it.

I've ordered a couple of those cards. Thanks for the link.
