Then it might be convenient to prepare these sub-directory and file location.
C: ¥ gm1601FW ¥ ISP ¥ Batch --- FlashRom_8.txt
C: ¥ LCD Holder --- rd_monitor_LHA_42&47.hex
--- rd_monitor_LSA_27&32.hex
--- rd_monitor_LSA+_42&47.hex
When the new firmware is prepared, only one of these, such as 'rd_monitor_LSA+_42&47.hex' will be sent.
The rewrite software needs to place a file by 'txt' format, thus received file needs to rewrite its file name.
Rd_monitor_LSA+_42&47.hex
After rewriting the file name, then this file needs to be placed into the sub-directly of:
C: ¥ gm1601FW ¥ ISP ¥ Batch - - - FlashRom_8.txt
Since the program always look for the file name of 'FlashRom_8.txt'.
When different set need to write, such as LSA_27&32, this new file should be copied under this sub-directly
And be re-named, then the FlashRom_8.txt will be over-written by the new information.
Copy 'rd_monitor_LSA_27&32.hex
Note: The old inside, LSA+_42&47 will be gone and new LSA_27&32 is replaced and becomes active.
