Changelog

21.6.0

• Top Speaker protect tune 21.5.0 → 21.6.0
  • Recharacterized and retuned to include new limit samples
  • Wael retuned XMAX gain to -24.3 (from -24.5) for slightly safer XMAX

21.5.1

• Bottom speaker protect tune uprev 21.5.0 → 21.5.1
  • Recharacterized and retuned to include new limit samples
• All top speaker tunes remain the same as in 21.5.0

21.5.0

• Updated 21.4.0_withWaelTuning with redc fallback values per customer request.
  • Top: 5.402 ohms
  • Bottom: 5.445 ohms
• This change in in the protect bins only. Cal and CalAndDiag bins remain the same as in 21.2.4.0_withWaelTuning

21.4.0_withWaelTuning

Updated Top Tuning xmax parameters by Wael No changes to bottom

21.4.0

Retune using R4 EVT samples. Firmware moved to 6.47.0 for protect, calibration, and diagnostics signal chains.

Changes in firmware between 6.45.0 and 6.47.0:

• Implemented a timeout feature that allows a maximum delay between the start of the BCLK and the start of the LRCLK. If the timeout is exceeded, an error notification is sent to the driver and the command is ignored. This addresses a host-side timing issue for these signals that could lead to a no-audio situation.
• Fixed an issue where repeated pause/resume commands could cause pops on the output.

21.2.3_ENG

Based on 21.2.2_ENG with HPF cutoff frequencies set to 150Hz for both top and bottom protect tunes

• Top speaker protect tune uprev 21.02.2eng → 21.02.3eng
• Bottom speaker protect tune uprev 21.02.0 → 21.02.1
• All other files same as 21.2.2_ENG

21.2.2_ENG

• Engineering build with Tmax of top protect tune fix in place. This is intended to resolve the overshoot issues seen in 21.2.0 but withthout the de-margin of Tmax that was done in 21.2.1
• All other files same as 21.2.0

21.2.1

• Updated Top thermal protect tune after reports of exceeding Tmax
• All other files same as 21.2.0

21.2.0

• Initial protect tune
