Hi Gabriel,


Try fixing CM-A510 related code:

mvBoardEnvSpec.h

...
...

/* CM-A510 */
#define CM_A510_MPP0_7                                 0x00000033
#define CM_A510_MPP8_15                                0x00445050
#define CM_A510_MPP16_23                               0x66664040
#define CM_A510_MPP24_31                               0x11111111
#define CM_A510_MPP32_39                               0x11111111
#define CM_A510_MPP40_47                               0x11111111
#define CM_A510_MPP48_55                               0x11111111
#define CM_A510_MPP56_63                               0x00111111
