i.MX6 UUU 沒有正確燒錄

yuhuiliu

我的板子是 6QP，想燒錄 4.14.62 的環境。
官方的 mfgtool 只有到 4.1.15 的版本，為了燒錄 BSP 4.14.62，有查到說要改用 UUU 燒錄。取 YOCTO 建置的 u-boot.imx, zImage, imx6qp-sabresd.dtb, rootfs.tar.bz2,
                           fsl-image-mfgtool-initramfs-imx_mfgtools.cpio.gz.u-boot (u-boot-mfgtool)
                           zImage_mfgtool (linux-imx-mfgtool)
試寫了 mx6qp.uuu：
  uuu_version 1.0.1  SDP: boot -f u-boot.imx -nojump
  SDP: write -f zImage_mfgtool -addr 0x12000000
  SDP: write -f imx6qp-sabresd.dtb -addr 0x18000000
  SDP: write -f fsl-image-mfgtool-initramfs-imx_mfgtools.cpio.gz.u-boot -addr 0x12C00000
  SDP: jump -f u-boot.imx -ivt
  FBK: ucp mksdcard.sh t:/tmp
  FBK: ucmd chmod 777 /tmp/mksdcard.sh
  FBK: ucmd /tmp/mksdcard.sh /dev/mmcblk3
  FBK: ucmd dd if=/dev/zero of=/dev/mmcblk3 bs=1k seek=4096 count=1
  FBK: ucmd sync
  FBK: ucmd echo 0 > /sys/block/mmcblk3boot0/force_ro
  FBK: ucp u-boot.imx t:/tmp
  FBK: ucmd dd if=/tmp/u-boot.imx of=/dev/mmcblk3boot0 bs=1K seek=32
  FBK: ucmd echo 1 > /sys/block/mmcblk3boot0/force_ro
  FBK: ucmd mmc bootpart enable 1 1 /dev/mmcblk3
  FBK: ucmd while [ ! -e /dev/mmcblk3p1 ]; do sleep 1; done
  FBK: ucmd mkfs.vfat /dev/mmcblk3p1
  FBK: ucmd mkdir -p /mnt/mmcblk3p1
  FBK: ucmd mount -t vfat /dev/mmcblk3p1 /mnt/mmcblk3p1
  FBK: ucp zImage t:/mnt/mmcblk3p1
  FBK: ucp imx6qp-sabresd.dtb t:/mnt/mmcblk3p1
  FBK: ucmd umount /mnt/mmcblk3p1
  FBK: ucmd mkfs.ext3 -F -E nodiscard /dev/mmcblk3p2
  FBK: ucmd mkdir -p /mnt/ext3
  FBK: ucmd mount /dev/mmcblk3p2 /mnt/ext3
  FBK: acmd tar -jxv -C /mnt/ext3
  FBK: ucp rootfs.tar.bz2 t:-
  FBK: Sync
  FBK: ucmd umount /mnt/ext3
  FBK: DONE

在終端機執行 ./uuu.exe ./mx6qp.uuu，燒錄過程的 log 看起來 u-boot、kernel 和 rootfs 都有燒入，但是開機後卻什麼都沒有(完全無 log，也沒開機)。
請問我的 uuu 語法有錯嗎?
附件裡有我的 uuu script 跟 燒錄 log。

我參照 example_kernel_emmc.uuu 重新寫了 uuu script：

  SDP: boot -f u-boot.imx
  # This command will be run when use SPL
  SDPU: write -f u-boot.imx -offset 0x57c00
  SDPU: jump
  # This command will be run when ROM support stream mode
  SDPS: boot -f u-boot.imx

  # use uboot burn bootloader to eMMC
  # becaue difference chip, offset is difference
  # you can use kernel to do that for specific boards
  FB: ucmd setenv fastboot_dev mmc
  FB: ucmd setenv mmcdev ${emmc_dev}
  FB: flash bootloader u-boot.imx
  FB: ucmd setenv emmc_cmd mmc partconf ${emmc_dev} 0 1 0;
  FB: ucmd if test "${emmc_skip_fb}" != "yes"; then run emmc_cmd; fi
  FB: ucmd setenv emmc_cmd mmc bootbus ${emmc_dev} 2 2 1;
  FB: ucmd if test "${emmc_skip_fb}" != "yes"; then run emmc_cmd; fi

  FB: ucmd setenv fastboot_buffer ${loadaddr}
  FB: download -f zImage
  FB: ucmd setenv fastboot_buffer ${fdt_addr}
  FB: download -f imx6qp-sabresd.dtb
  FB: ucmd setenv fastboot_buffer ${initrd_addr}
  FB: download -f fsl-image-mfgtool-initramfs-imx_mfgtools.cpio.gz.u-boot
  #FB: ucmd setenv bootargs console=${console},${baudrate} earlycon=${earlycon},${baudrate}
  FB: acmd ${kboot} ${loadaddr} ${initrd_addr} ${fdt_addr}

  # get mmc dev number from kernel command line
  # Wait for emmc
  FBK: ucmd while [ ! -e /dev/mmcblk*boot0 ]; do sleep 1; echo "wait for /dev/mmcblk*boot* appear"; done;

  # serach emmc device number, if your platform have more than two emmc chip, please echo dev number >/tmp/mmcdev
  FBK: ucmd dev=`ls /dev/mmcblk*boot*`; dev=($dev); dev=${dev[0]}; dev=${dev#/dev/mmcblk}; dev=${dev%boot*}; echo $dev > /tmp/mmcdev;

  # create partition
  FBK: ucmd mmc=`cat /tmp/mmcdev`; PARTSTR=$'10M,650M,0c\n660M,,83\n'; echo "$PARTSTR" | sfdisk --force /dev/mmcblk${mmc}

  FBK: ucmd mmc=`cat /tmp/mmcdev`; dd if=/dev/zero of=/dev/mmcblk${mmc} bs=1k seek=4096 count=1
  FBK: ucmd sync
  # you can enable below command to write boot partition. but offset is difference at difference platform
  # burn uboot
  #FBK: ucmd mmc=`cat /tmp/mmcdev`; echo 0 > /sys/block/mmcblk${mmc}boot0/force_ro
  #FBK: ucp  u-boot.imx t:/tmp
  #FBK: ucmd mmc=`cat /tmp/mmcdev`; dd if=/tmp/u-boot.imx of=/dev/mmc${mmc}boot0 bs=1K seek=32
  #FBK: ucmd mmc=`cat /tmp/mmcdev`; echo 1 > /sys/block/mmcblk${mmc}boot0/force_ro
  FBK: ucmd mmc=`cat /tmp/mmcdev`; while [ ! -e /dev/mmcblk${mmc}p1 ]; do sleep 1; done
  FBK: ucmd mmc=`cat /tmp/mmcdev`; mkfs.vfat /dev/mmcblk${mmc}p1
  # burn kernel
  FBK: ucmd mmc=`cat /tmp/mmcdev`; mkdir -p /mnt/fat
  FBK: ucmd mmc=`cat /tmp/mmcdev`; mount -t vfat /dev/mmcblk${mmc}p1 /mnt/fat
  FBK: ucp  zImage t:/mnt/fat
  FBK: ucp  imx6qp-sabresd.dtb t:/mnt/fat
  FBK: ucmd umount /mnt/fat
  # burn rootfs
  FBK: ucmd mmc=`cat /tmp/mmcdev`; mkfs.ext3 -F -E nodiscard /dev/mmcblk${mmc}p2
  FBK: ucmd mkdir -p /mnt/ext3
  FBK: ucmd mmc=`cat /tmp/mmcdev`; mount /dev/mmcblk${mmc}p2 /mnt/ext3
  FBK: acmd export EXTRACT_UNSAFE_SYMLINKS=1; tar -jx -C /mnt/ext3

  FBK: ucp  moudules.tar.bz2 t:-
  FBK: Sync
  FBK: ucmd umount /mnt/ext3
  FBK: DONE

雖然這個燒錄，但常常在燒 rootfs 時出錯：Start Cmd:FBK: ucp  lvirootfs.tar.bz2 t:-

找到解決方法：
修改 uuu source code 中 libuuu/fastboot.h
  - size_t m_Maxsize_pre_cmd = 0x10000;
+ size_t m_Maxsize_pre_cmd = 0x1000;
