Working on the OTA web UI. Some questions: a) Flashing and changing the boot partition outputs some irritating overflow and "??" log messages: OVMS > ota flash vfs /sd/ovms3.done Current running partition is: ota_0 Target partition is: ota_1 Source image is 1480592 bytes in size Preparing flash partition... Flashing image partition... Setting boot partition... OTA flash was successful Flashed 1480592 bytes from /sd/ovms3.done Next boot will be from 'ota_1' I (1316956) esp_image: segment 0: paddr=0x00810020 vaddr=0x3f400020 size=0x5879c (362396) map I (1317156) esp_image: segment 1: paddr=0x008687c4 vaddr=0x3ffb0000 size=0x0382c ( 14380) I (1317156) esp_image: segment 2: paddr=0x0086bff8 vaddr=0x40080000 size=0x00400 ( 1024) 0x40080000: _WindowOverflow4 at /home/balzer/esp/esp-idf/components/freertos/./xtensa_vectors.S:1685 I (1317166) esp_image: segment 3: paddr=0x0086c400 vaddr=0x40080400 size=0x03c10 ( 15376) I (1317176) esp_image: segment 4: paddr=0x00870018 vaddr=0x400d0018 size=0xfb154 (1028436) map 0x400d0018: _flash_cache_start at ??:?

The flashed partitions seem to work correctly. b) How do you get back to the factory partition if something went so wrong you can't use the "ota" command? I would have expected "make flash" to reset the boot partition to "factory", as all flashes are only done there, but it doesn't. So if you're on another partition with a broken firmware, how do you recover? Is there a way to set the boot partition using esptool.py? c) ota flash http still gives me a DNS lookup error on any other host than api.openvehicles.com and fails to download from api.openvehicles.com, regardless of the type of network (wifi/modem). OVMS > ota flash http www.google.com/ovms3.bin Current running partition is: factory Target partition is: ota_0 Download firmware from www.google.com/ovms3.bin to ota_0 Error: Request failed W (666891) net: DNS lookup on www.google.com failed err=200 OVMS > ota flash http api.openvehicles.com/test.bin Current running partition is: factory Target partition is: ota_0 Download firmware from api.openvehicles.com/test.bin to ota_0 […dead, needs reset] Is this a local problem of mine?
