I'm trying to flash ATSAME51N19 chip using Atmel-ICE, as it was having old bootloader and firmware. But getting error Verifying Flash...Failed! address=0x0000 expected=0x80 actual=0xff
And The fuses are
AC_BIAS0 = 0x01
ADC0_BIASCOMP = 0x07
ADC0_BIASREFBUF = 0x07
ADC0_BIASR2R = 0x07
ADC1_BIASCOMP = 0x07
ADC1_BIASREFBUF = 0x07
ADC1_BIASR2R = 0x07
USB_TRANSN = 0x09
USB_TRANSP = 0x19
USB_TRIM = 0x06
ROOM_TEMP_VAL_INT = 0x1D
ROOM_TEMP_VAL_DEC = 0x08
HOT_TEMP_VAL_INT = 0x69
HOT_TEMP_VAL_DEC = 0x00
ROOM_INT1V_VAL = 0x01
HOT_INT1V_VAL = 0x02
ROOM_ADC_VAL_PTAT = 0xAD8
HOT_ADC_VAL_PTAT = 0xD5D
ROOM_ADC_VAL_CTAT = 0xB71
HOT_ADC_VAL_CTAT = 0x954

BOD33_ACTION = RESET

WDT_EWOFFSET = CYC16384
WDT_WEN = [ ]
NVMCTRL_REGION_LOCKS = 0xFFFFFFFF
SW0_WORD_0 = 0x1FF07FD (valid)
SW0_WORD_1 = 0x1B29 (valid)

TEMP_LOG_WORD_1 = 0xD5DAD802 (valid)
TEMP_LOG_WORD_2 = 0xFF954B71 (valid)
USER_WORD_0 = 0xDE9A9239 (valid)
USER_WORD_1 = 0xAEECFFB1 (valid)
USER_WORD_2 = 0xFFFFFFFF (valid)
I think the issue is with the fuses how do I reset all the fuses and do programming? How can I solve this flashing issue.
