Does anyone try to replace the sd card in pixhawk by emmc?
we had try to connect the CMD, CK, D0~D4 to emmc BGA pin, and also include VSS, VDDF, VDDI, but failed to startup.
Then we try a small pcb board convert emmc to sd, we connect the sd card to computer, copy file to sd, everything is ok, but when we connect CMD, CK, D0~D4 from pixhawk to sd, it failed again.
At last, we connect the pixhawk to tf card directly, it could startup, no problem.
So I suppose it maybe some wrong from emmc to SD, maybe something different in STM32 or the driver of APM, Does anyone have experience to do that?
