Hi,

We have developed a platform using S32V234 as the main controller, and have made many boards,among them there are some emmc can't be formatted. There is a 32G emmc(MTFC32GAKAEEF-AIT) per board. the process is, first run u-boot,then run nfsboot,I can login,then run fdisk,the partition table can be printed, the first partition starts at 2048 ends at 524287,Size 255M,Id c, Type W95 FAT32(LBA),and then run mkfs.vfat -n boot /dev/mmcblk0p1,it suspends.

I have tried to change the start position of the first partition and have checked the partition table has changed,but it still can't be formatted.

What can I do except change a new eMMC chip?

Hi, 

there is howto document related to eMMC, but I'm not sure if it covers your issue ( not tested with SBC board ) . But you can try it - https://community.nxp.com/docs/DOC-340293
