How to store file/folder in EMMC flash of LS1046ARDB Kit and how to access it on next power on?

Please refer to the following procedure to write file to MMC card in Linux.

Partition the mmc card with fdisk

$ fdisk /dev/mmcblk0

$ fdisk -l /dev/mmcblk0

$ mkfs.ext2 /dev/mmcblk0p1

$ mount /dev/mmcblk0p1 /mnt/

$ cp -r test_file /mnt/

Please note you could use scp command to copy your file to the target board.

Please refer to the following to access file in MMC under u-boot.

=> ext2load <interface> [<dev[:part]> [<addr> [<filename> [bytes [pos]]]]]

For example:

=> ext2load mmc 0:1 0xa0000000 test_file

Thank you for the reply. But I couldn't access mmcblk0. No such file or directory was coming when i gave fdisk /dev/mmcblk0 command.

Please run "fdisk -l" on your target board.

I have run that command and it is coming as in the attached text file.

You need to use RCW with emmc enabled.

Please specify rcw_qspi as the following to enable emmc in RCW file in configs/board/ls1043ardb/manifest in flex-builder.

rcw_qspi=$FBOUTDIR/firmware/rcw/ls1046ardb/RR_FFSSPPPH_1133_5559/rcw_1600_qspiboot_emmc.bin.swapped

Then run the following command "flex-builder -c atf -m ls1046ardb", you will regenerate flexbuild_lsdk2004/build/firmware/atf/ls1046ardb/bl2_qspi.pbl and fip_uboot.bin.

Please deploy them to bl2_qspi.pbl at 0x00000000, bl2_qspi.pbl at 0x100000 on QSPI flash.

Then go to u-boot prompt to check whether it is is possible to get MMC information as the following.

> mmcinfo
Device: FSL_SDHC
Manufacturer ID: fe
OEM: 14e
Name: P1XXX
Bus Speed: 52000000
Mode : MMC High Speed (52MHz)
Rd Block Len: 512

Erase Group Size: 512 KiB
HC WP Group Size: 4 MiB
User Capacity: 3.6 GiB
Boot Capacity: 2 MiB ENH
RPMB Capacity: 128 KiB ENH

Please check whether you could get the following message in Linux Kernel booting up log.

mmcblk0: mmc0:0001 P1XXXX 3.60 GiB
[ 3.685716] NET: Registered protocol family 10

Thanks,

I deployed those files still mmcinfo is coming as device not found. Bootlog attached.

Re: LS1046ARDB KIT

yipingwang — Wed, 18 Nov 2020 07:30:41 GMT

In file flexbuild_lsdk2004/configs/board/ls1046ardb/manifest, please modify rcw_qspi as the following.

rcw_qspi=$FBOUTDIR/firmware/rcw/ls1046ardb/RR_FFSSPPPH_1133_5559/rcw_1600_qspiboot_emmc.bin

Then rebuild atf with the following command

$ flex-builder -c atf -m ls1046ardb

You will get bl2_qspi.pbl and fip_uboot.bin in build/firmware/atf/ls1046ardb/ .

Please refer to the following command to deploy these two files to QSPI flash bank4.

Please go to QSPI vBank 0 and execute the following commands.

=> sf probe 0:1
=> tftp 0xa0000000 bl2_qspi.pbl
=> sf erase 0x0 +$filesize && sf write 0xa0000000 0x0 $filesize

=> tftp 0xa0000000 fip_uboot.bin
=> sf erase 0x100000 +$filesize && sf write 0xa0000000 0x100000 $filesize

Then execute the following command to go to bank4.

=> cpld reset altbank

Re: LS1046ARDB KIT

I tried this but still issue remains the same. No mmc card present is coming

I have verified my previously procedure, it works.

I attached my images for you.

I have used the files sent by you .But it is not getting updated.Even for the files which i have created also same issue.Is there anything wrong with the way i am flashing it to the qspi?

Re: LS1046ARDB KIT

yipingwang — Fri, 20 Nov 2020 08:26:04 GMT

First please go to QSPI vBank0

Then execute the following commands.

=> sf probe 0:1
=> tftp 0xa0000000 bl2_qspi.pbl
=> sf erase 0x0 +$filesize && sf write 0xa0000000 0x0 $filesize

=> tftp 0xa0000000 fip_uboot.bin
=> sf erase 0x100000 +$filesize && sf write 0xa0000000 0x100000 $filesize

Then execute the following command to go to bank4.

=> cpld reset altbank

Note: you could get vbank information from u-boot console log.

If your problem remains, please capture your console log to me to do more investigation.

Thank you so much for the reply. It worked. I was doing from bank4 .So it was not getting updated. I could write files to emmc flash also. "sync" command i gave after cp -r to write to emmc flash. How to erase files in emmc and how to format emmc flash ?

Re: LS1046ARDB KIT

yipingwang — Mon, 23 Nov 2020 08:23:19 GMT

You could format emmc in Linux as the following.

$ fdisk -l /dev/mmcblk0

Disk /dev/mmcblk0: 7.5 GiB, 8001683456 bytes, 15628288 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x5a5f34b3
Device Boot Start End Sectors Size Id Type
/dev/mmcblk0p1 2048 15628287 15626240 7.5G 83 Linux

$ mkfs.ext2 /dev/mmcblk0p1

Re: LS1046ARDB KIT

IB2020 — Tue, 24 Nov 2020 04:12:09 GMT

Thank you for the reply. But if i want to delete a single folder without formatting emmc what is the command i should use?

Re: LS1046ARDB KIT

yipingwang — Fri, 27 Nov 2020 03:12:42 GMT

Under Linux, execute the following command

$ mount -t ext2 /dev/mmcblk0p1 /mnt

go to /mnt folder to remove the specified folder.

$ umount /mnt
