Dear all

Please let me know the Latest firmware release and bootloader names of Skystar AM60 AM32 4in1 esc. Since one esc was not showing in AM32 Configurator So --
- I have flashed the esc with wrong firmware I think .
- I have used esc_configurator_1.93 to flash.
- It flashed successfully with the file named AM32_SKYSTARS_AM60_V2_F421_2.20.hex all escs
- Afterward I checked in the AM32 configurator, all escs were showing.
- So I modified the kv value to 1980 and saved.
- After saving I rechecked on the AM32 configurator, it shows all 4 motors but cannot read.

I request you to kindly help me in this regard and provide me with the names of  Latest firmware release and bootloader of Skystar AM60 AM32 4in1 esc and also the procedure (steps to program).

what flight stack are you using? ardu,inav,beta?

SKYSTARS F722 APP WIFI HD3 Flight Controller

FC flashed with INAV.

Try this, if you haven't already: https://esc-configurator.com/ , with the props off and battery on. Also make sure that you have selected the esc protocol as Dshot 600 or more

When I zoomed in on your esc pic, I see e230 written on the MCUs, if it is e230, the MCUs are not f421 , try flashing the skystar e230 hex file.

Hex file withe e230 suffix for AM 60 is available on am32 website. You may have to flash the bootloader also, for that I think 'stlink' device may work, the two pads (golden circular ones) from each of the MCUs should be clock and data, you have to solder jumper wires from stlink device's clk, data to those pads and also ground to any ground point on the esc, then use stlink utility to erase the current bootloader and firmware. Download the correct bootloader bin file from AM32 website. Flash boot loader on 0x08000000 address , if the bootloader file is in Hex format, no need of address. Then flash firmware , which indeed is in Hex format.


Ps : In your case, if you have only flashed wrong firmware (not bootloader) , you may not have to flash bootloader again, it will have the correct bootloader. In any case, you would need the above mentioned device 'stlink' to flash the correct firmware.
