how can i create a partition on new emmc?

novemer — Wed, 10 Jun 2015 14:36:55 GMT

hi all

i make a board based on imx283 evk, but repalce SD card with emmc(SanDisk SDIN5D2-16G) .data0-3,clk.cmd.now there is a problem:the emmc is new one,not formatted,even no partition.so i can not use it directly.debug window txt out:new high speed.....14.8Gb/unknown partition table.how can i create a new patition and format it?

i tried "fdisk",but when i execute"fdisk /dev/mmcblk0",system is down.

i tried again with a sd card that i canfix it use card reader.

1,insert a formatted sd card, powerup, txt out:.....14.8Gb/mmcblk0p1;

2,execut"fdisk /dev/mmcblk0",type "m" for help,and type "d" for delete patition,type "w" and quit, powerdown;

3,powerup,txt out:....14.8Gb/unknown patition table;

4, i can not do anything unless put the sd card to cardreader and format with PC.

Hi Xu Wang,

I didn't understand you completely, which boot device are you using?

And could you please paste the bootlog here?

Best Regards,

Isaí

hi Isai,

thanks for reply.

my board boot from nand flash,and the system files are in nand flash too.i just replace sd card with emmc chip.i want to use it for storage.

here is the bootlog:

Re: how can i create a partition on new emmc?

novemer — Thu, 11 Jun 2015 07:06:14 GMT

"fdisk" command is useless,if i type"fdisk /dev/mmcblk0",the system is down.

Re: how can i create a partition on new emmc?

isaigaspar — Thu, 11 Jun 2015 18:12:44 GMT

Ok, let's try this, check if you can read/write on the eMMC, you can try 'dd if=/dev/zero of=/dev/mmcblk0 bs=512 count=512.' Just to make sure it's not a disk issue.

It seems more like a hardware issue, could you please provide the SD/eMMC schematic and your code for pin configuration?

Best regards,

Isai

Isai,

thanks for reply.

i tried 'dd if=/dev/zero of=/dev/mmcblk0 bs=512 count=512.' it does not work too, system is down.

can i send emai to you, for i don't know how to upload pdf file.

best regards.

Hi Wang,

You can attach a file using the advanced editor located at the top right of the reply section. Once you have selected the advanced editor there will be an "Attach" option. You can use the "Insert Image" option as well.

Have a good one,

Isai,

here is part of sch.

IMX283_CORE is a core board base on offical EVM,and it is work well on other projects.i just replace SD card with EMMC.

UPDATE:

1,emmc is :SDIN5D2-16G;

2,SSP0_WP is pull-down to GND.

wang

Re: how can i create a partition on new emmc?

isaigaspar — Mon, 15 Jun 2015 21:49:40 GMT

Hi Wang,

It seems that your schematic is correct.

According to your bootlog you are using battery power, this may cause problems if the regulators are not configured correctly.

In chapter 11 of the Reference Manual:

"If the system is operating from the DC-DC converter and is using more
current than the linear regulators can supply, then the VDDD, VDDA, and VDDIO rails
will droop when 5V is attached and the system may brownout and shut down."

Please make sure that the microcontroller always has valid voltages during eMMC or SD Card R/W operations, which is the time when they use more current. This may be the cause of your shut down.

If you believe this is a Linux problem, you can try R/W on the eMMC in Uboot :

- Choose the right mmc instance of your eMMC (You can check the available devices with "mmc list")

U-Boot > mmc dev #instance

Example:

U-Boot > mmc dev 2

mmc2(part 0) is current device

- If you are not sure that's the right one you can see its properties with: mmcinfo.

Example:

U-Boot > mmcinfo

Device: FSL_SDHC

Manufacturer ID: 45

OEM: 100

Name: SEM08

Tran Speed: 52000000

Rd Block Len: 512

MMC version 4.41

High Capacity: Yes

Capacity: 7.4 GiB

Bus Width: 8-bit

- Now you can write/read on it

U-Boot > mmc write 0x10000000 0x600 0x10

MMC write: dev # 2, block # 1536, count 16 ... 16 blocks write: OK

U-Boot > mmc read 0x10000000 0x600 0x10

MMC read: dev # 2, block # 1536, count 16 ... 16 blocks read: OK

Best regards,

Isai

Thanks for replay, as a now one in embedded linux, I have no idea about bootlog, I will try what you say.

I don't use battery suplly, I just short battery pin and vcc pin.

Hi Xu Wang,

If your u-boot doesn't have that command you need to add it in your board configuration file mx28evk.h

#define CONFIG_CMD_MMC

Best regards,
