ThinkNode M5 & Meshastic 2.7.14.e959000 Alpha: invalid header: 0x�ESP-ROM:esp32s3-20210327
Hi everyone,
I used the Meshtastic Webflasher to upgrade my ThinkNode M5 firmware to version 2.7.14.e959000 Alpha. After flashing, the device no longer boots. When I connect via serial console, I see the following output:
invalid header: 0x�ESP-ROM:esp32s3-20210327
Build: Mar 27 2021
rst:0x10 (RTCWDT_RTC_RST), boot:0x2b (SPI_FAST_FLASH_BOOT)
invalid header: 0x3a343034
invalid header: 0x3a343034
invalid header: 0x3a343034
invalid header: 0x3a343034
invalid header: 0x3a343034
Has anyone run into this issue before?
Any guidance on how to recover the device and get it working again would be greatly appreciated!
