Hello.
I'm using an S3A6 microcontroller from RENESAS, JFLASH software (v 6.62) and FLASHER PORTABLE PLUS.
My program has two different ".srec" files:
1) Program Code starting at 0xA000.
2) Bootloader code starting at address 0x0000
First, I open Program Code with JFlash software. Then, I use the option "File --> Merge data file" from JFlash to merge Program Code with Bootloader.
When I use this merge with JFlash and J-LINK mode to burn the S3A6, the PCB works well at first.
However, when I download the merge to the flasher's memory (using "File --> Download config & data file to Flasher") and then try to burn the microcontroller in stand-alone mode using PROG button, it doesn't work at first. If I push PROG button one more time, the PCB starts to work well.
The option "... Read Back --> Entire Chip" reveals that the first time I used PROG button, the flasher only programmed the Bootloader section. The second time, the flasher programmed the Program Code section correctly.
Why is this happening? How can I program the entire chip in one go?
