Hi Daniel,
I hope you are doing great.
You could look at the table in the 2.1Command Options Chapter.
DK6 Production Flash Programmer User Guide JN-UG-3127

Please look at the next examples.
The following command will first erase all the flash and then flash the binary (binary.bin) at address 0x00000000:
DK6Programmer.exe -s COM56 -e FLASH -p binary.bin
As another example, the following command will first flash the binary (binary.bin) at address 0x00000000 and then erase one page of flash (512 bytes) at offset = 64Kb (the assumption is made here that size of binary.bin is less than 64K):
DK6Programmer.exe -s COM56 -p binary.bin -e FLASH:512@65536
Regards,
Mario
