Incorrect functionality of UART mode

[madurani]

I tried to configure on RobinNanoV1.2 UART mode(on axis y) with drivers tmc2208, tmc2209, according "how to" on link https://www.youtube.com/watch?v=7ShcFKXrVHo. Everything worked on first time, but motor after finishing given motion (even though it works properly) shivers and hisses loudly(sound is very similar to sound of television that cant detect signal), however when I switch back to step/dir mode motion of motor is correct(same motor&driver).

Look like that issue is related with kind of stepper motors, because when i use old motors https://www.aliexpress.com/item/32811604070.html?spm=a2g0s.9042311.0.0.27424c4d79bGIL, then problem with hissing sounds occurs, though when I use motor https://www.aliexpress.com/item/32811604070.html?spm=a2g0s.9042311.0.0.27424c4d79bGIL it works correctly(without mentioned sound). Is it possible to modify marlin configuration for old kind of motors?

What was done for UART configuration: 1 three jumpers under driver were removed 2 cable was soldered on pins of driver(uart and R8) and connected to pin of board (PA9) 3 marlin configuration: Configuration.h >> #define X_DRIVER_TYPE TMC2208 or #define X_DRIVER_TYPE TMC220 //according installed driver Configuration_adv.h: #define X_CURRENT 636 // max current of motor is 0.9A Configuration_adv.h: #define X_MICROSTEPS 16 Configuration_adv.h: #define HYBRID_THRESHOLD Configuration_adv.h: #define X_HYBRID_THRESHOLD 100 pins_MKS_ROBIN_NANO.h #define Y_SERIAL_TX_PIN PA9 pins_MKS_ROBIN_NANO.h #define Y_SERIAL_RX_PIN PA9

Driver tmc2208 and tmc2209 behaves the same way

Here is debug outputs from M122:

After adding all 5 drivers to UART mode + dual z + sensor less on xy axis, all work as expected, without mentioned sound(reason of issue wasn't find)

This is OK.

Which sort of memory(flash, eeprom, sdcard) use RobinNanoV1.2 for store of parameters from command M500, when is set up in marlin?

/
// EEPROM
//
#if EITHER(NO_EEPROM_SELECTED, FLASH_EEPROM_EMULATION)
  #define FLASH_EEPROM_EMULATION
  #define EEPROM_PAGE_SIZE     (0x800U) // 2KB
  #define EEPROM_START_ADDRESS (0x8000000UL + (STM32_FLASH_SIZE) * 1024UL - (EEPROM_PAGE_SIZE) * 2UL)
  #define MARLIN_EEPROM_SIZE    EEPROM_PAGE_SIZE

Flash memory?
