TM903_P1_D0002
1.Add pull-up resistors to MMCmicro CMD and DAT[3:0]
D D
2.Audio PA design is not correct.
Single End input feed to IN-, but not IN+
Feed back from OUT+ to IN-,or from OUT- to IN+;
If PA is NCP2890, need R301,R302, R64, and R65; else CP2296, do need R301 R302 R64 R65
TM903_P1_D0003
For PCB layout, chang net around U23 and U24
