Marlin 2.0 and 32bit board for JGAURORA A5. It is workable?

Hello, colleagues.
Anybody thinking about upgrade A5 to 32bit board?
After searching and evaluating the existing solutions (SKR1.3 board, Lerge K) for me is most suitable seems using a:
МКС SGen_L board+set of TMC2130 or TMC2208 drivers+default TFT display+Marlin 2.0.
Or may be already checked solutions are exist?

Comments
1.МКС SGen_L board
2.TMC2130 drivers (X,Y,Z,E0)
3. Default TFT display (custom community firmware)
4. Marlin 2.0 bugfix
Marlin firmware was configured according manual from MKS supplier and based on example configuration in Marlin package. All functions (display control, motors, temperature sensors) are operational. Mesh bed leveling is working, SPI control for TMC2130 drivers also working as usual.
But when i try start a print a gcode from USB flash or directly from PC - the printer make a preheating a bed and extruder.... and nothing happened. Printing is not started. I have tried 5 times - same result.
I have checked a temperature of extruder - it has some fluctuation, but no more as usual.
Also i have added a capacitor 5000 mkf in +5V circuit near a temperature sensor connector on board - no any results.
What can be a reason?
Configuration file is attached
It seems that SKR 1.3 is really optimal board for A5 upgrade.
Which stepper motor driver you apply?
M913 Y50
M913 Z1
M913 E1
#define GRID_MAX_POINTS_Y GRID_MAX_POINTS_X
#define Z_PROBE_SPEED_SLOW 50
#define Z_CLEARANCE_BETWEEN_PROBES 1
#define Z_AFTER_PROBING 10
Do you use a BL-Touch for auto probing, did you encounter any problems with it?
Z_MIN_PROBE_REPEATABILITY_TEST
@aeroburnerkn: Some features require the emergency parser which itself calls for an LCD Display (other than the A5 TFT). You can either install one of those or deactivate the features requiring the emergency parser in the first place.
There is a base configuration that should work for the A5. Last time I tried the 2.0 development version with the original A5 control board I couldn't get some of the more advanced features working, but that was before the official 2.0 release. A lot has improved since then, so I see no harm in giving it a try. Be sure to know how to revert to the version you are currently running. If you rely on settings saved with M500, you should write down all settings before you upgrade so you can easily restore them later. These notes will also be helpful on adjusting the base configuration.
If you never did this before, you may want to consult one of the many excellent video tutorials on how to download, configure, compile and upload Marlin.
