Mod-fw of UHSDR 2.11.91m1

I'm posting a new version of my mod-firmware 2.11.91m1. At the request of RA1OKO added:
- Option to allow 10 W transmission in the CB civilian band, relevant for the Russian Federation - Debug / Exper. Settings -> CB 10W TX Enable.
- Option of temporary (within the session) memorizing filter settings for each mode of each range - Debug / Exper. Settings -> Remember BWs on bands. It would be possible to store the settings not only temporarily, if we find free space in the non-volatile memory for a 16-bit 10x20 array. I did not find.

Sure. I used to do that, my callsign is even in Hall of Fame. The problem is reaching agreement with UHSDR. They consider many of my developments useless and even harmful.

I agree that the code should be tested on all firmware versions. Until the end of the year or the end of January, I will have the opportunity to test on an F7 processor and a 480x320 display. Still, I would like to see a list of improvements that the UHSDR group considers interesting and useful, if not difficult. If there will be no material problems, I will also solder the OVI40 H7 for the tests. Now I have some financial problems, sorry.

I checked all the F7 and H7 series STMs
UHSDR 2.11.91m1 program.
STM32F767_ZIT6 is OK
STM32H743_ZIT6 is OK !!!!!
STM32H743_ZIT6U is wrong the program does not start
One TRX STM32H743_ZIT6U has a white screen, the led is black.
the other TRX STM32H743_ZIT6U has a black screen, the led is black.
I guess the STM32H743_ZIT6U chips are different from the STM32H743_ZIT6.
It's probably not a problem that "STM32H743_ZIT6U" is 480MHz and STM32H743_ZIT6 is 400MHz.
The STM32H743_ZIT6U chip is faster and costs less money (Farnell, Mouser) Why?

Because it is obsolete...
Farnell has old revision and wants to sell them. Both are marked as 400MHz. Starting from the revision 6 these cores have 480MHz, if the core has "V" marking on the case, then it is capable of run at 480MHz. Please read the manual about the changes they made. Also, there is no such marking as "U" in ordering info looking to description in datasheet.

As previously said: obsolete. Your chip is almost two years old... Must be an intermediate version or "something". As said, look to the current pdf from ST: https://www.st.com/resource/en/datasheet/stm32h743zi.pdf, page 352.
Directly from ST factory:

Firmware for "small MCU" are also compiled, with FreeDV cut out. Here is the complete 2.11.91m1 firmware for "small MCU":

I temporarily stopped compiling monochrome firmware versions. I am a not so-so programmer, all my attempts to introduce monochrome styles into one firmware have failed, but I do not lose hope. Here is sepia for F7. Wouldn't it be too much impudence on my part to ask for a photo of Sparrow with this firmware at a B/W waterfall?

I called the ST and have the answer for "U" marking - there is no silicon change, the "U" marking means that the chip price contains fee for licensing some linked libraries for example MicroEJ (Java). So why it doesn't work is a question to author.
Also found some explanation in nucleo boards:

I have not made all modifications to my code that did not concern the executable code. But this is fixable. Need hardware for testing. And thanks for the photo!

I read somewhere about the possibility of CPU clocking from "DDC Module 2". In this case, the processor is not forced to start until stable generation is established. Is this not the case on the left?
