GKaURTbV: Bug report 3750 seems similar: https://bugs.openwrt.org/index.php?do=details&task_id=3750 Unfortunatelly, I cannot provide such detailed info, because I don't have a serial connection on my CPE210 v1. If I can try something - please, let me know. |

apcameron: The TP-Link CPE 610 v1 has the same problem. |

apcameron: See [[https://bugs.openwrt.org/index.php?do=details&task_id=3782|https://bugs.openwrt.org/index.php?do=details&task_id=3782]] for the log related to this bug |

GKaURTbV: So this change fixed CPE210v1 boot loop for me: It got included in the master OpenWrt branch: Can we get this in 21.02 branch as well, please? It missed both rc2 and rc3 now. |

bjonglez: Backported as r16181-7a4bd9cc51: https://git.openwrt.org/7a4bd9cc518933d61099f109ce050c03afdc1c83 Please test 21.02-SNAPSHOT in a few days to confirm it works fine. |

GKaURTbV: Thanks, Baptiste, I can confirm that 21.02.0 branch now works as well. Here is the start of the kernel log:

My only issue left with OpenWrt right now is that if for some reason I need to restart dnsmasq without rebooting my router, it fails to load the hostnames I have set up on the device. The issue and a fix is described in FS#3090: Can something be done about that? Thanks for the great work and for putting up with users like me :) |
GKaURTbV:
Supply the following if possible:
Device problem occurs on:
TP-Link CPE210 v1
Software versions of OpenWrt/LEDE release, packages, etc.
21.02.0-rc1
Steps to reproduce
I had OpenWrt 19.07.7 installed on a TP-Link CPE210 v1, but with the old ar71xx arch. The device worked just fine - no complaints whatsoever.
From there, I tried sysupgrading to 21.02.0-rc1 with the sysupgrade firmware (https://downloads.openwrt.org/releases/21.02.0-rc1/targets/ath79/generic/openwrt-21.02.0-rc1-ath79-generic-tplink_cpe210-v1-squashfs-sysupgrade.bin), and because of the arch change to ath79, while sysupgrading I choose NOT to keep settings. Judging by the LEDs - the device went into some kind of a bootloop.
I managed to recover the device back to stock, and from there - I tried installing the factory firmware (https://downloads.openwrt.org/releases/21.02.0-rc1/targets/ath79/generic/openwrt-21.02.0-rc1-ath79-generic-tplink_cpe210-v1-squashfs-factory.bin), just to check if it made any difference.
Sadly, no luck the second time either - the same bootloop again.
So then I was back to stock, and the to 19.07.7, and I have a working device again.
Just wanted to report the failure, in contrast with my tries with 21.02.0-rc1 on the TP-LINK Archer C7 v5 and the TP-Link TL-WR1043ND v1, which seem to work just fine.
