Dear Radek,
Hello, I would like to add that.I direct the contents of the file“.s19” copy and paste into the PC serial communication assistant to send, interface display download success, but I run the program, the function is not normal, however I use BDM to download files“.s19”, run the program function is normal, I wonder whether my ".PRM" partition error? Or need to parse the file“.s19” and then send? What do I need to do, help me see, thank you very much!
Hi Jixiang,
1. There is a problem with interrupt vectors in your application.
The PE generated vector table at default vectors position 0xFF80~0xFFFF. This area is already used by Bootloader. You have to create vector table somewhere else in Flash or RAM.
Please switch PE CPU inspector into the Advanced or Expert mode and set addresses for Reset vector table (for example 0xEEFA) and Interrupt vector table (for example 0xEE80).
2. The s19 file must be converted by SRecCvt utility prior loading into MCU. That will manage that S records will have correct address format and that S-record size is exactly 32B (it simplifies parser in bootloader code – in Srec.c file).
3. The flow control of your PC terminal must be set for XON/XOFF mode. Unfortunately, I do not know PC terminal from your picture. You should select “b” and send s19 file content as a text file. Since programming needs some time, we must use flow control. Otherwise, receive buffer will overflow.
I hope it helps you.
Have a great day,
Radek

Dear Radek,
Thank you for your patience!
I basically understand the process, thank you very much! But when I use the software "SRecCvt-GUI", found that there is no S12GN32 driver, I need to manually add this driver, in order to convert ".S19" this file, how do I need to add it? How do you fill out the address? Thank you very much. Here's my screenshot:
The following figure is my "PE" tool to configure the memory after the screenshot:
Dear Radek,
Add a little more,I just directly modify the APP source code compiled through the BDM download to the microcontroller, can be successfully downloaded, but the program can not run, can not achieve the function, is it my ROM partition error? Thank you!
But when I put the "reset vactor address" to 0xFFFA, "interrupt vactor address" to 0xFF80, and then re compiled, downloaded to the microcontroller through the BDM, to be able to run normally, the function is normal, table, table.
Figure：
Here's a bit of my personal understanding, is that right?
You can see the address 0XFF80, 0XFFFA no problem, they do not overlap!Do not know how to understand, thank you! Do you need any changes?
This is just my point of view, you follow your instructions to me, thank you very much! Best illustrated!
Dear Radek,
Thank you very much！According to your suggestion I revised the BOOTLOADER and APP program.
This is a screenshot of the BOOTLOADER program changes：
In the BOOTLOADER program only in this place will "effe" instead of "effa", other places remain unchanged.
Here is a screenshot of the APP program:
Attachment is my revised "BOOTLOADER" and "APP" source, you help me look at this right? If you have the wrong place, please take your screenshot to help me analyze the show, thanks!
Dear Radek,
Hello! I looked at the document, using the serial port to connect the circuit board and the computer, download the BOOTLOADER program has been able to communicate, the host computer can receive information, but also to erase success,As shown in the following figure:
Then I used the "ProcessorExpert" tool to create a new project "GN32App", and then modified the memory address in the ".PRM" file, as shown in the documentation:
This is a compiled file“.s19”
I still do not understand a bit, the compiled file “.s19”,downloaded to the microcontroller through the BOOTLOADER, how to parse the file“.s19”,You gave me a software"SRecCvt-GUI", there is no driver on the S12GN32, I tried to add a, no success, can you help me add one?The main task is to compile the new project files “.s19”downloaded to the microcontroller through the BOOTLOADER, how to do, how to parse the file“.s19”, what is it? Thank you
