Hi Ti,

I want to partition the emmc in uboot, and my machine boot from sdcard now.

I don't want to partition the emmc via fastboot, Is the 6ao1.1's uboot support  partition the emmc?

    Hi Haili Zeng,

    Which fastboot operation are you referring to?
    I am assuming you are referring to 'fastboot oem format' command.

    All the commands that fastboot does should be doable by u-boot.


    Regards,
    Vishal

    Hi Vishal Mahaveer ,

    I want to execute 'fastboot oem format' command on uboot, what should I do?
    What command should I input the uboot command line, or what function should I call？

    Equivalent of 'fastboot oem format' in u-boot console is 'gpt write mmc 1 $partitions'

    Snippet from u-boot source

    static void cb_oem(struct usb_ep *ep, struct usb_request *req)
{
        char *cmd = req->buf;
        char cmdbuf[32];

        reset_fastboot_cmd();

#ifdef CONFIG_FASTBOOT_FLASH_MMC_DEV
        if (strncmp("format", cmd + 4, 6) == 0) {
                sprintf(cmdbuf, "gpt write mmc %x $partitions",
                        CONFIG_FASTBOOT_FLASH_MMC_DEV);
                add_fastboot_cmd(0, cmdbuf);
        } else
#endif
