From the oldest (first) to the newest (last)
Warning Notice:
Firmware releases starting with 2017.02b are not backward-compatible with older units manufactured before 17-Feb-2017. Such SP3 units, running older firmware will not normally accept firmware revisions issued after Feb-2017 of type mpfs22.
New SP3 units shipped after 17-Feb-2017 will NOT work with old firmware and will reject all revisions prior to 2017.02b, upon upload.
Use SP3_mpfs22.bin for new units later than 2017.02 and use SP3_mpfs21.bin for old units.
Adapted to new batch of USBX board revision XR6, (backwards compatible with
the previous rev XR5e and with old non-high-res boards). 2018.01c
Fixed TriggerOut delay feature, (faulty - always 0 since 2016.08b MkVI)
Added special handling of DTS over SPDIF (lack of decoder interrupts worked-around by polling). This prevents loss sync on change such as pause or FF track etc.
Fixed IR remote 1dB increments instead of 0.5dB, and fixed blinking large volume display
during IR volume change.
Speeded up Ethernet by about 50% by optimizing TCP/IP packet memory buffering.
Ported "calling home server" feature, similar to BDP-x and BAX1 products, on startup whenever IP address changes.
(enabled only in SP3).
Increased processor clock in Standby state to avoid internal communication errors on startup with HDMI and DSP boards, when "Ethernet in Standby" option is set to off.
Allowed #10TEST222 command in Standby state to allow enabling the diagnostic "dot" commands such as for example ".e" .
Added #10LIST00 command to list a contents of the internal flash memory.
Updated DHCP and upload page behavior 2018.04D
Including HDMI HSR72Q firmware upgrade 46.52 in SP3_noboot.bin
to fix some Apple TV issues. After upload the bin file, got to MISCELLANEOUS/UPDATE MENU: and execute HDMI update functions manually for 3 on board processors, one at a time.
2019.01a
Removed HDMI HSR72Q firmware upgrade 46.52 because MDS programming algorithm has changed and the programming feature would not work in the current SP3 software..
Introduced option SERVER CALLS ENABLE/DISABLE in MISCELLANEOUS to disable server calls from the SP3.
2019.03d
Reduced volume boost VOL_TRIM_AUX_SUB_HDMI_r by 12dB.
Bug fix in hdmi_chip_firmware_program. 2019.04a
Modified HSR72Q programming function
Added call home action on IP reassignment by DHCP
Ported DHCP.c mod (221) by DM from BDA3 correcting netbios
name format sent to DHCP server. Increased TCP_PIC_RAM_SIZE
from 2000 to 5000 and max n.of sockets from 2 to 3. 2019.05b
Added support for HSR82T, timing, fixed dac_mute, dac_set_rate. 2020.01e MkVII
Adjusted timing preventing loss of HDMI AuxL/R. Changed DEFAULT_DLYSCALE_HSR82T. (2020.01e MkVIII) 2020.06a
changed MENU_DAC_UNMUTE_DLY_100ms 7-->20
fixes Auxiliary L&R output pop or loss of play 2020.10a
Increased power on internal voltage switching delays to prevent infrequent
I2C bus crash on power op after a very long standby time (reported with
HSR82 HDMI card). 2021.01a
