I have a WRTNode 2p Based on the mt7628an.

By inserting a sd on the board and installing the appropriate kernel module, the chip recognizes the SD card, but the partitions are not. (Obviously mmcblk0 is not mountable)

At this point thinking that my sd was not formatted I formatted it from LEDE, I have created a partition and formatted it.
I removed and re-inserted the sd, at this point the partition was recognized and I could mount it and copy data on it.

I than removed the SD and connected it to a PC, the pc does not see the partitions I just created.
I tried to put the sd back on the device and LEDE recognizes it and also finds the partitions.

Thinking that it was my PC I changed with another one but also in that case the card remains inaccessible.

I then partitioned again and formatted the card from a PC. LEDE does not see the partition.
I have no idea where the problem might be.

I also tested this with the stable release of LEDE and the problem still occurs.
