Hi Sir, Currently I’m trying to test sd card on the yellow (Kingston 4G HC4), and I can see mmc0 information in dmesg as below ![image](https://us1.discourse-cdn.com/flex016/uploads/mangoh/original/2X/8/858ebca5bf2cc1485ca83eac95f3ea25ca5cf736.png) but some problems have been occurred when I try to mount SD card, I would like to ask whether there are any steps that need to perform? (need to format or start something?) ![image](https://us1.discourse-cdn.com/flex016/uploads/mangoh/original/2X/9/9b1216dfab68b230d4509badeadb2f16618fb695.png) ---

I have tried to format to fat16 and fat32 via linux on my PC , but they cannot be mount on mangoh. FAT16 ![image](https://us1.discourse-cdn.com/flex016/uploads/mangoh/original/2X/1/1e80ba6df3f2cecc9f0b6f18037ef008506bbf9b.png) FAT32 ![image](https://us1.discourse-cdn.com/flex016/uploads/mangoh/original/2X/7/7e8c4cdceca7315648dccbd6f60acf9dfa1f6e57.png) ---

The warning seems to be normal. [https://e2e.ti.com/support/processors/f/processors-forum/212784/disk-dev-mtdblock0-doesn-t-contain-a-valid-partition-table](https://e2e.ti.com/support/processors/f/processors-forum/212784/disk-dev-mtdblock0-doesn-t-contain-a-valid-partition-table) What is the error message when you mount the card? ``` mkdir -p /tmp/sdcard /bin/mount -t auto -o sync /dev/mmcblk0p1 "/tmp/sdcard" ``` Also what is the return of this one? `cat /sys/kernel/debug/mmc0/ios` ---

Hi jyijyi, It’s very thanks for your support, I can mount the SD on my mangOH now . But I still have a problem that system will hang after I execute the `fdisk -ul` command. ![image](https://us1.discourse-cdn.com/flex016/uploads/mangoh/original/2X/c/c1cb7d9e9f05de6993925fc9847a7d33df5acd14.png) Do you have the same problem? ---

Do you find problem to fdisk in Ubuntu PC? BTW, does this help? > [@Lsusb not found, unable to mount usb drive](https://mangoh.discourse.group/t/lsusb-not-found-unable-to-mount-usb-drive/1893/2): > > I noticed that fdisk -l has issues. I forgot to check whether a bug has been reported for this or not. I will try to look into it tomorrow. What I do remember is that fdisk -l /dev/mtdblk0 will work. ---
