IMX6 EMMC从4.4换到5.1版无法烧录

[jhp1234]

有个问题 请问一下，原IM6的EMMC是SANDISK 4.41版，现在因为EMMC停产，EMMC换成5.1版的，按照官方的方法说是5.1版EMMC要降成4.41版来使用，修改了LTIB里的LINUX EMMC驱动：

/* workaround: support emmc 4.5 cards to work at emmc 4.4 mode */
if (card->ext_csd.rev > {
printk(KERN_ERR "%s: unrecognised EXT_CSD revision %d\n",
mmc_hostname(card->host), card->ext_csd.rev);
err = -EINVAL;
goto out;
}

生成uImage，放到Profiles\MX6Q Linux Update\OS Firmware下，但MFGTOOL一直卡在<CMD state="Updater" type="push" body="$ echo 1 > /sys/devices/platform/sdhci-esdhc-imx.3/mmc_host/mmc0/mmc0:0001/boot_config">access boot partition 1</CMD>这一行 ，即显示access boot partition 1，不再往下执行，这种情况要怎么改？

CPU是IMX6Q, 用的LTIB L3.0.35_4.1.0, MFGTOOL也是对应的

EMMC驱动mmc.c修改了这里，完全按官方的方法改的

/* workaround: support emmc 4.5 cards to work at emmc 4.4 mode */
if (card->ext_csd.rev > {
printk(KERN_ERR "%s: unrecognised EXT_CSD revision %d\n",
mmc_hostname(card->host), card->ext_csd.rev);
err = -EINVAL;
goto out;
}

不知道为什么 > 8）不见了

You can refer to https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/EMMC-5-0-and-EMMC-5-1-work-on-i-MX6/ta-p...

[Rita_Wang]

Yes, you only need the modify the rev as we recommend, does it work well now?

[jhp1234]

I followed the method NXP recommanded, but the mfgtool can not work well, it always stops on   

"<CMD state="Updater" type="push" body="$ echo 1 > /sys/devices/platform/sdhci-esdhc-imx.3/mmc_host/mmc0/mmc0:0001/boot_config">access boot partition 1</CMD>"

the mfgtool log error info:

ModuleID[2] LevelID[10]: ExecuteCommand--Push[WndIndex:0], Body is $ ls /dev/*
ModuleID[2] LevelID[10]: ExecuteCommand--Push[WndIndex:0], Body is $ dd if=/dev/zero of=/dev/mmcblk0 bs=512 seek=1024 count=16
ModuleID[2] LevelID[10]: ExecuteCommand--Push[WndIndex:0], Body is $ echo 1 > /sys/devices/platform/sdhci-esdhc-imx.3/mmc_host/mmc0/mmc0:0001/boot_config
ModuleID[2] LevelID[1]: PortMgrDlg(0)--MxHidDevice--Command Push(no file) excute failed

If cancel this command, mfgtool seems to write complete, but the device can not start.

Could you tell me why?

[Rita_Wang]

Have you rebuild the the firmware uImage used for MfgTool ? You need to rebuild the uImage for Mfgtool, and then Update the uImage in Mfgtool .

[jhp1234]

Yes, I have, and replaced the uImage for mfgtool.
