[MOD][MCU] cs-x Mod MTCB/C MCU firmware (SoundPatched) - MTCB Software Development

Modified firmware MCU MTCB/MTCC in the part of the presets of the sound processor (Sound Modified)
thanks to the esteemed @Hal9k_ for advice on creating a topic on the forum for English-speaking users and respected @typos1 and @Wadzio for their help and tips on attaching MCU firmware files to the thread
link to Russian mirror
All the modified MCU firmware are made on the basis of the original firmware of the corresponding suffixes and versions. The following values ​​are displayed:
-- for the low-frequency band of the equalizer became: frequency 60Hz, Q-factor 0.5;
-- for the mid-range of the equalizer became: frequency 500Hz, quality factor 0.75;
-- for the high-frequency band of the equalizer became: frequency 15kHz, Q-factor 0.75;
-- for loudness compensation: frequency 250 Hz, 5 dB level;
-- for the subwoofer channel became: the cutoff frequency of the low-pass filter 120Hz, antiphase output

Great, thanks, hopefully we ll sort the attachment problem soon.
Can you do a version of the attached MTCC KLD9 v2.98 as well ? Thanks

Looks interesting and guess it's time to read up before doing a flash..
Anything we should know before hand?
Lol..might have to find a hill top with a bit to sun coming in and good internet connection in case I screwed things up and flash this and a new rom.. will make this old unit feel like a best again..
Thanks for the continued work.. the Chinese should take note..

Just flash the MCU as normal.

as far as I know, the latest current MCU firmware for KGL-suffix version 2.83
if you post it, then I can modify it for you
P.S.
already found this version of the KGL MCU firmware and modify it soon

Will this also work for the RK3188 KGL?

Yes, because the MCU firmware is universal and does not depend on the specific type of Rokchip processor RK3066(PX2) or RK3188(PX3)

Why is there a size difference in the 2 files (RK3066 dmcu vs RK3188 dmcu) if they are the same and compatible?

Is your question general or specific?
-- if specific, please provide examples of these specific files that need to be compared
-- if common, the firmware of the MCUs are related to the Rocchip processors the same ratio as, for example, to the Intel Pentium or other processors, becouse are not associated with either one or the other
Perhaps I did not quite understand your question, becouse English is not my native language
In addition, I do not know the head units on the RK3066 with the MCU firmware dmcu.img

What I wanted to say was, in this thread https://forum.xda-developers.com/showthread.php?t=3246386 it says mcu files work on both RK3066 and RK3188 units, but the file sizes of the mcu files are different between RK3066 and RK3188 units and for RK3066 it's an mcu file and for RK3188 it's an dmcu file.
For example MTCD-JY-2.06sp (Sound Patched) from https://forum.xda-developers.com/an...ent/mod-cs-x-mod-mtcd-e-mcu-firmware-t3816042 is a different file size as the mcu file MTCB-JY-2.86m from the OP of this thread.

Since the head units of Microntek consist of two components (MCU and CPU), in fact, the dependence of the MCU firmware from the Microntek platforms is as follows:
- first appeared Microntek platform MTCB family, based on the IAP15L4K61S2 microcontroller from the MCS-51 family and a ARM processor coreboard on the dual-core Rockchip RK3066(PX2) from the Cortex A9 (ARMv7) family (Android 4.2.2). Microcontroller from MCS-51 family is 8-bit and MCU firmware code depends of Instruction set and was approximately 45 kB for a max total user size of 56 kByte (file mcu.img);
-- a little later appeared the new ARM processor coreboard on the quad-core Rockchip RK3188(PX3) from the Cortex A9 (ARMv7) family (Android 4.4.4). MCU remained the same as before (file mcu.img);
-- a little later appeared the software-updated Microntek platform MTCC family, based on the same IAP15L4K61S2 microcontroller from the MCS-51 family and a ARM processor coreboard on the same quad-core Rockchip RK3188(PX3) from the Cortex A9 (ARMv7) family (but Android 5.1.1). By adding a new functionality MCU firmware code was approximately 55 kB for a max total user size of 56 kByte (file mcu.img). For the long-range increase of the MCU firmware code there was not enough free space left;
- to solve the problem of lack of free space for firmware binary code in the IAP15L4K61S2 microcontroller, Microntek developers have prepared a new platform MTCD based on a new microcontroller from another family
-- in a result appeared the new Microntek platform MTCD family, based on the other STM32F091 microcontroller from the ARM Cortex-M0 family and a ARM processor coreboard on the same quad-core Rockchip RK3188(PX3) from the Cortex A9 (ARMv7) family (Android 5.1.1). Microcontroller from stm32f0 family is 32-bit and MCU firmware code depends of Instruction set and was approximately 160 kB for a max total user size of 248 kByte (file dmcu.img);
-- at later appeared the software-updated Microntek platform MTCE family, based on the same STM32F091 microcontroller from the ARM Cortex-M0 family and a ARM processor coreboard on the same quad-core Rockchip RK3188(PX3) from the Cortex A9 (ARMv7) family (Android 5.1.1) and new pin-compatible coreboard on octa-core Rockchip RK3368(PX5) from the Cortex A53 (ARMv7) family (Android 6.0.1) and new pin-compatible coreboard on quad-core Rockchip RK3188(PX3) from the Cortex A9 (ARMv7) family (Android 7.1.1) and new pin-compatible coreboard on octa-core Rockchip RK3368(PX5) from the Cortex A53 (ARMv7) family (Android 8.0). Now by adding a new functionality MCU firmware code was approximately 230 kB for a max total user size of 248 kByte (file dmcu.img).

Thanx for explaining it in so much detail. Now I understand the differences very well.
