<i class="pstatus"> This post was last edited by IC Crawler on 2022-9-28 00:17</i> After successfully compiling openwrt, the following error occurred when using pack to package the firmware: ``` mbr size = 4096 mbr magic softw411 disk name=boot-resource disk name=env disk name=boot disk name=rootfs ERROR: dl file rootfs.fex size too large ERROR: filename = rootfs.fex ERROR: dl_file_size = 119040 sector ERROR: part_size = 45360 sector update_for_part_info -1 ERROR: update mbr file fail ERROR: update_mbr failed ``` ##Solution: Modify the value 45360 in the file `device/config/chips/v853/configs/vision/linux-4.9/sys_partition.fex` and change it to a value greater than 119040. (I changed 45360 to 120000) After the modification, you can use pack to complete the firmware packaging. The output result at the end after successful packaging is: ``` Dragon execute image.cfg SUCCESS ! ----------image is at---------- 69M /media/yq/M/workspace/MCU/allwinner/tina-v853/out/v853/vision/openwrt/v853_linux_vision_uart0.img pack finish ``` Reference:<https: %e6%b1%82%e5%8a%a9-v853-pack%e7%9a%84%e6%97%b6%e5%80%99%e6%8a%a5%e9%94%99="" 2108="" 5="" bbs.aw-ol.com="" topic=""> </https:>

There is still a lot of information and problem-solving posts on the Allwinner forum, and the support is pretty good.

There are no routines and interface documents for mpp. How can this be called abundant information?

Thank you for sharing. The information of domestic devices needs to be further improved.
