Elprotronic GangFlasher ST provides convenient procedure for programming boards with ST MPx microprocessor inside. Within this procedure called User-Defined boards programming it is possible to automatically adapt user Device Trees. They provide non-recoverable peripherals and external devices as a static structure. One of GangFlasher (GF) functionalities is export of used minimal Device Tree (DTmin) and direct user correction of used nodes via DTmin configuration file. Let us consider one of microprocessor (MPU) Vendor example board, in this case it will be Karo TXMP-1570 board.

GangFlasher-CLI example

Firstly compile GF-CLI with F_LoadOS() functionality (argument cmdcmd equal 3). GF-CLI functionalities are described in details in GF-CLI tutorial. To setup Karo in GF User-Defined mode please set in configuration file and load it with usage of function F_LoadTargetConfig():

MCU_name		Karo
UserDefined_Board_1_Name		Karo 
UserDefined_Board_1_tfa_File		/home/UserXX/Karo/tf-a-stm32mp157c-txmp-1570-trusted.stm32
UserDefined_Board_1_zImage_File		/home/UserXX/Karo/fip-stm32mp157c-txmp-1570-trusted.bin

Compile and run this configuration, in UART console there will be shown log:

INFO:           DT: bsec_probe() OK
INFO:           DT: dt_open_and_check() OK
