Updated

[Initial release] MARAFW rel 3.13-498

  1. [Improvement] Revamped firmware loading process, requiring MARATools v1.1 and up
  2. [Improvement] Improved tuning algorithm, efficiency and safety checks
  3. [Improvement] Allows miners to boot and initialize when one or more hashboards have EEPROM errors
  4. [Improvement] Miners with only 1 working fan will enter sleep mode automatically after reboot, to avoid HW damage
  5. [Improvement] Miners with only 2 working fans will mine at half hash rate, to avoid HW damage
  6. [Improvement] Miners start to mine during the preheat phase, utilizing the power more effectively
  7. [Improvement] Miner will load previous tuning profile after a reboot. In case the resulting hashrate is low, an automatic re-tune is triggered.
  8. [Improvement] Minor UI/UX improvements
  9. [Fix] Pool settings are correctly restored when uninstalling MARAFW
  10. [Fix] LED indicators now more closely match stock behavior
  11. [Fix] Fixed an issue with S19 Pro miners creating an excess amount of duplicate shares, leading to low hashrate
  12. [Feature] Added tuning progress bar
  13. [Feature] Added support for Alphaminer PSUs
  14. [Feature] Added support for S21 BHB68606 variant
  15. [Feature] Added option to stop mining in case all pools are dead, to conserve power. Mining will automatically resume once at least one pool becomes available.
  16. [Feature] Added option to disable preheat timeout, meant to be used in very cold climates where the preheat takes longer.

[Initial release] MARAFW rel 3.12-401

Release Notes: updated 3/21/24

Added:

  1. API commands for license key
  2. support for Antminer T21
  3. support for APW11A 3-Phase PSU, for T21
  4. Added "MARAFW" to API SystemOverview
  5. hashboard hashrate in the log when it's lower than 80%
  6. "Clean Cache" option which clears tuning results, reboots miner, and triggers a retune

Changed:

  1. power consumption to 25W in sleep mode
  2. recovery temp from 60 to 70, shutdown temp from 85 to 90 for Antminer S19
  3. check for low hash rate when recovering from under-clocking starts after 15 minutes
  4. force retune if last cache rate is lower than 0.99 of baseline
  5. override fixed fan percentage to be applied even in sleep mode
  6. PID algorithm for thermal control

Fixed:

  1. ADC readings in BM1398 ASICs
  2. S19j 88 ASICs version issue
  3. panic when block number in block header is invalid
