8.8 Updating PNEV7462B/C board firmware (flash and EEPROM memory)
PN7462AU flash memory can be updated either by using SWD interface and LPC-Link 2
debug probe or from primary bootloader mode (USB MSD).
8.9 Updating flash/EEPROM via SWD interface
Ensure that LPC-Link2 is connected to PNEV7462B board (see Fig 75) and follow the
steps below.

Once the flash tool started the correct connection and flash driver file needs to be
specified. For PN7462AU-C03-00 the correct flash driver is PN7xxxxx_158k.cfx when
updating flash memory content and the base address is 0x203000. When updating
EEPROM settings appropriate driver is PN7xxxxx_EE_3_5k.cfx and the base address is
0x201200.
