Hi, i solved this using the low-cost adapter like the ucapps site.
(Hi to everyone,
I got recently a midibox seq v4 lite from the fleamarket, so i did't build by myself, works, but not the sdcard.
I use a sdhc 4gb, partitioned to 900 MB with a FAT16, in the MIOS terminal give me this error:
[4384.701] [disk_initialize] error while checking for SD Card (status 0)
[4384.703] [FILE] Failed to open root directory - error status: 13
[4385.700] SD Card disconnected
There's a card pcb with the slot, not the low-cost solution, look at the connection seem all ok, the only thing is the ground that only one it's soldered.
I would try to make the low-cost adapter on the ucapps site, but if someone know how to check or maybe i wrong something...i would like to see if it's all ok before build the adaptor.
I'm new in electronics and in midibox but i'm able to solder some wire.
Thanks)
