xyzzy: 2020-05-01: The issue remains with snapshot build dated "Thu Apr 30 07:24:28 2020" Every time I run into the issue with flashing the latest snapshot, which I do every time ther's a new image available, even if I can see the image file is of the wrong size, I can always recover by flashing the latest stable release which currently is 19.07.2. I've encountered this issue several times before over the past year and it can be spotted by looking at the size of the image file. Image files that do not work on my 16MB FLASH version of the ZBT-WG3526, always has the same image file size as the 32 MB FLASH version of the router! If you look at the snapshot files dated "Sun Apr 12 18:20:31 2020" for the 16 MB and compared it to the 32 MB version, they are identical in size. The 32 MB version will install but will not run. A working image file for the ZBT-WG3526 (16M) apears to have a size of 4 718 784 to 4 718 881 bytes. Below is a list of released versions of image files for ZBT-WG3526 (16M): 2019-02-03 15:10 4 718 784 openwrt-18.06.2-ramips-mt7621-zbt-wg3526-16M-squashfs-sysupgrade.bin Todays image file for the 16 MB version is identical in size compared with the 32 MB version: 2020-04-12 18:38 5 243 203 openwrt-ramips-mt7621-zbtlink_zbt-wg3526-16m-squashfs-sysupgrade.bin |
camel: is it possible to find out on which day the size was increased ? - maybe that would help to tell to DEVS and to do a rollback of that change .... ? |
xyzzy: The latest stable release is 4608.3 KB in size and is dated Sun May 17, 2020. This image works fine. This date is later than the date I first encountered the problem. By using the config.buildinfo files from releases/19.07.3/targets/ramips/mt7621/ and snapshots/targets/ramips/mt7621/, whoever makes the .config file should be able to figure out what is wrong. I did a file diff and the first few lines can be seen in the attached screen dump. |
