Fixed - Ts1022 Firmware

I will assume the TS1022 is a Rockchip (RK3288/RK3328 class) or similar ARM SoC board with a SPI NOR flash, U-Boot as bootloader, and a Linux kernel. The “fixed” firmware refers to patched U-Boot + environment variables that solve:

  1. Incorrect memory timing → random crashes
  2. Corrupt environment sector → boot loop
  3. Watchdog timeout too short → reboot before kernel loads
  4. Invalid boot device priority → fails to fall back to eMMC/USB

The Future: What’s Next for ts1022 Firmware?

The manufacturer has released a roadmap following the successful "ts1022 firmware fixed" update: ts1022 firmware fixed

  • June 2024: Android 12 upgrade (beta).
  • August 2024: Fixed CEC and HDMI handshake issues.
  • December 2024: Security patch update (Android security level December 2024).

You can track official announcements at the ts1022 support portal (search for ts1022.com/firmware). I will assume the TS1022 is a Rockchip

5.1 If boot still loops after fix

  • Check power supply ripple (must be <50mV at 5V).
  • Verify SPI flash health: sf probe; sf test 0x60000 0x20000 inside U-Boot.

4. Post-fix behavior improvements

| 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 | The Future: What’s Next for ts1022 Firmware


Method 1: OTA Update (If Device Boots)

  1. Go to Settings > Device Preferences > About > System Update.
  2. Tap "Check for updates."
  3. If you see version 2.1.4, download and install.
  4. The device will reboot. Wait 5 minutes.

6. Advanced: building the fixed firmware from source

git clone https://github.com/rockchip/u-boot
cd u-boot
git checkout ts1022-fixed-branch  # or apply patches manually
make ts1022_defconfig
make CROSS_COMPILE=aarch64-linux-gnu-
# Output: u-boot-rockchip.bin
# Convert to SPI format:
tools/mkimage -n rk3328 -T rksd -d tpl/u-boot-spl.bin idbloader.img
cat u-boot.bin >> idbloader.img

Flash idbloader.img at offset 0x40 (for RK3328).
