Ts1022 Firmware Fixed May 2026

| Before fix | After fix | |------------|-----------| | Boots 1/3 attempts | Boots 10/10 attempts | | Watchdog resets at kernel decompression | Kernel fully loads before watchdog fires | | Environment corruption every ~50 power cycles | Redundant env + CRC check → zero corruption | | DDR errors on warm reboot | Force re-training → stable | | No USB recovery | usb_boot fallback works |

Community forums and official support tickets confirm the fix. Here are three representative quotes:

“We have 47 TS1022 units monitoring air quality in a museum. After updating to v2.1.8, we’ve seen zero reboots in 3 weeks. The old firmware required weekly power cycles. The ‘ts1022 firmware fixed’ search led us to the patch – thank you.”
— Michael R., Building Automation Engineer “We have 47 TS1022 units monitoring air quality

“The Modbus CRC bug was killing our production line. We had to implement software retries on the PLC side. Now with v2.1.8, the error rate dropped from 3.2% to 0.003% (likely environmental noise). This is the stable release we’ve been waiting for.”
— Elena V., Industrial Controls Specialist

“I almost returned my TS1022 until I found the firmware fix. The web UI would freeze every hour. Now it’s rock solid. Don’t skip this update.”
— Carlos D., Makerspace Technician
