6.1.1.2
Command setting example
When S1C17 processor is selected
Example: Save FLS program fwr17701v11.saf to S5U1C17001H internal memory.
With erasing routine address 0x48 and writing routine address 0x80
(gdb) c17 fwlp. fwr17701v11.saf 0x48 0x80
Example: When flash programming voltage and communication packet size setting are required
Set the communication packet size to 128 bytes, the flash erase voltage to 7.5 V, and the write
voltage to 7.0 V, and save the FLS program fwr17651v11.saf to the S5U1C17001H internal
memory.
For erasing routine address 0x9c and writing routine address 0x68
(gdb)c17 fwlp fwr17651v11.saf 0x9c 0x68 “-v7.5-7.0 –s128”
Example: To execute write-back function
Set the write-back routine address to 0x10 and the write-back FLS program size to 1312 bytes, and
save the dedicated write-back function execution FLS program fwr17f57_writeback.saf to the
S5U1C17001H internal memory.
For erasing routine address 0x9c and writing routine address 0x68
(gdb)c17 fwlp fwr17f57_writeback.saf 0x9c 0x68 “-v7.5-7.0 –s128 –b0x10-1312”
