In the case the ready led and error led switch on and not blinking. i read the user manual it shows:

– either the board ID is not recognized by the FW (bad FW versions used)– or there is a problem with the SPI (no connection between the MCU and the L6470via the SPI)– or there is no 5 V - 45 V DC power supply.i'm sure the power supply is fine then i replace the L6470 chip problem still there.
