I integrated mender 2.0.0 into my imx6ull14x14 board,which is running linux 4.14.78. When I test the mender upgrade,I met the error. I want help. ```auto INFO[0000] Loaded configuration file: /etc/mender/mender.conf module=config INFO[0000] Mender running on partition: /dev/mmcblk1p2 module=main INFO[0001] API Gateway certificate

Hi @gmeat, Welcome to Mender Hub. Lets break out the interesting parts. This means the update has started and it is downloading the necessary bytes, ```auto INFO[0112] opening device /dev/mmcblk1p3 for writing module=block_device INFO[0112] partition /dev/mmcblk1p3 size: 1392508928 module=block_device ``` Here it seems that you keep losing network connectivity and the mender client resumes a couple of times. ```auto ERRO[0200] Download connection broken: unexpected EOF module=update_resumer INFO[0200] Resuming download in 1m0s module=update_resumer INFO[0260] Attempting to resume artifact download from offset 3505622 module=update_resumer ERRO[0330] Download connection broken: unexpected EOF module=update_resumer INFO[0330] Resuming download in 1m0s module=update_resumer INFO[0390] Attempting to resume artifact download from offset 7011181 module=update_resumer ERRO[0490] Download connection broken: unexpected EOF module=update_resumer INFO[0490] Resuming download in 1m0s module=update_resumer INFO[0550] Attempting to resume artifact download from offset 25213188 module=update_resumer ERRO[0616] Download connection broken: unexpected EOF module=update_resumer ``` And here it finishes the download due to to many network interruptions (I think, @kacf can you confirm? ), but as it is not complete the checksum is wrong and the update is marked as failed. ```auto INFO[0616] wrote 199274489/1392508928 bytes of update to device /dev/mmcblk1p3 module=dual_rootfs_device ERRO[0617] Artifact install failed: reader: error reading data: invalid checksum; expected: [d0660816b5124436a5f1a186d309f3260337c63854ae5246f81836c66cc04cae]; actual: [f59da380dc12e8604cfe64883e38d958f903cfb68e23a6d1f0d41784e3e09e69] module=state ``` [/quote] ---

Hi Mirzak： Thank you for your reply. I used “ping [mender.sgw.com](http://mender.sgw.com)”( [mender.sgw.com](http://mender.sgw.com) is my mender server IP) command to check the network,and it never disconnect when the board downloading the .mender file. ---

Hi Mirzak &Kacf: Thank you for your help!!! I have success to download the .mender file after I expand the memery to 8GB of server. But now I met the other problem. When the board reboot,it haven’t boot from Rootfs B(/dev/mmcblk1p3), it still boot from RootfsA(/dev/mmcblk1p2). How to set it boot from the rootfsB after update-install ? ``` INFO[7641] State transition: inventory-update [Sync] -> check-wait [Idle] module=mender ``` INFO[7641] State transition: check-wait [Idle] -\> update-check [Sync] module=mender INFO[7641] Correct request for getting image from: [https://s3.sgw.com:9000/mender-artifact-storage/83cbafbb-06d0-40bc-9f0c-00c9d615dc6a?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Content-Sha256=UNSIGNED-PAYLOAD&X-Amz-Credential=mender-deployments%2F20190711%2Fus-east-1%2Fs3%2Faws4\_request&X-Amz-Date=20190711T080812Z&X-Amz-Expires=86400&X-Amz-SignedHeaders=host&response-content-type=application%2Fvnd.mender-artifact&X-Amz-Signature=e526ba95dab25b1ea9573a6a5ac1dd14701c32af44e2629523823559721330d9](https://s3.sgw.com:9000/mender-artifact-storage/83cbafbb-06d0-40bc-9f0c-00c9d615dc6a?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Content-Sha256=UNSIGNED-PAYLOAD&X-Amz-Credential=mender-deployments%2F20190711%2Fus-east-1%2Fs3%2Faws4_request&X-Amz-Date=20190711T080812Z&X-Amz-Expires=86400&X-Amz-SignedHeaders=host&response-content-type=application%2Fvnd.mender-artifact&X-Amz-Signature=e526ba95dab25b1ea9573a6a5ac1dd14701c32af44e2629523823559721330d9) [name: SGW6010-v0.2; devices: [imx6ull14x14evk]] module=client\_update INFO[7641] State transition: update-check [Sync] -\> update-fetch [Download\_Enter] module=mender INFO[7641] Running Mender version 2.0.0 module=deployment\_logger INFO[7641] State transition: update-fetch [Download\_Enter] -\> update-store [Download\_Enter] module=mender INFO[7642] no public key was provided for authenticating the artifact module=installer INFO[7642] native sector size of block device /dev/mmcblk1p3 is 512, we will write in chunks of 1048576 module=dual\_rootfs\_device INFO[7642] opening device /dev/mmcblk1p3 for writing module=block\_device INFO[7642] partition /dev/mmcblk1p3 size: 973078528 module=block\_device ERRO[7781] Download connection broken: read tcp 192.168.0.128:34508-\>192.168.0.149:9000: read: connection reset by peer module=update\_resumer INFO[7781] Resuming download in 1m0s module=update\_resumer INFO[7841] Attempting to resume artifact download from offset 2129366 module=update\_resumer INFO[8349] wrote 973078528/973078528 bytes of update to device /dev/mmcblk1p3 module=dual\_rootfs\_device INFO[8350] State transition: update-store [Download\_Enter] -\> update-after-store [Download\_Leave] module=mender INFO[8350] State transition: update-after-store [Download\_Leave] -\> update-install [ArtifactInstall] module=mender INFO[8350] Enabling partition with new image installed to be a boot candidate: 3 module=dual\_rootfs\_device INFO[8350] State transition: update-install [ArtifactInstall] -\> reboot [ArtifactReboot\_Enter] module=mender INFO[8350] rebooting device(s) module=state INFO[8350] Mender rebooting from active partition: /dev/mmcblk1p2 module=dual\_rootfs\_device [OK] Stopped target Host and Network Name Lookups.`Preformatted text` [OK] Stopped target Bluetooth.

The log is incomplete so hard to comment. Anyway, please verify the integration by following this checklist, [https://docs.mender.io/2.0/devices/yocto-project/bootloader-support/u-boot/integration-checklist](https://docs.mender.io/2.0/devices/yocto-project/bootloader-support/u-boot/integration-checklist)
