BAF concept , transmitting .elf file through CAN
Im using SPC58C80E5, working on Autodevkit studio,

}
}
first im executing this code LED is blinking after that when i send CAN message with ID 7F0 and data AA the LEDs becoming freeze if im resetting also they are in freeze, after that using SPC5 Flash programmer trying to flash the file but when i select the interface and click connect its loading not connecting, and also the port is not used by any other applications .
Im using ICP CON i-7530 as intermediate between PC and microcontroller to communicate with CAN . IN CAN im using PB[9] and PB[10] according to the SPC58EC user manual , check wt is happening please help with it.
