ROM monitor for m30624fgpfp controller

Hi all,
I've been working with the M16c62A controller, but now renesas recommend me to change to the m16c62p version and is supposed that no changes in the pinout is needed.
I've been able to use flashsta for downloading but when I try to run KD30 it hangs.
Does someone has the rom monitor for the m30624fgpfp controller?.

Any recomendation?

Thanks in advance

Hi lince

I could help your with a monitor which suits, but are your sure the interrupts are on the right address in sec30.inc?

.lword 0FF900h ; uart1 trance (for user)
.lword 0FF900h ; uart1 receive (for user)

m16c/62p

Hi Gomez,
Yes, the uart1 interrupt are configured in this way.
The problem is that I'm not able to run the program with the Kd30 or excute it step by step, it hangs. I cannot execute the first instruction step by step in the ncrt0.a30 file prior the sect30.inc file is allocated.

I see with the oscilloscope that the micro and the pc interchange information when I press the reset button in the KD30 software.

Thank you for your help. If you have more comments please let me know. I appreciate them.

Hi lince

that's a monitor for my m30624fgafp and should work with your m30624fgpfp too.
The monitor runs fine with KD30.4

Let me know when you have more problems.

I've forgotten. You can build your own monitor.

m16c62p monitor program

Hi Gomez, thank you for the file, I've donwloaded it with the flashsta and same result as with mine.
This microcontroller is a brand new one, Is trange I'll try to check if all the signals are right in the controller. But I'm a bit lost with this problem and I have no other controller for change and test.

Do you speak spanish ?.

Thnaks a lot for your support. Have you experience with the migration from A version to the P version?. Do you know if any hardware change must be implemented?.

Regards.

Have you tried to compile your own monitor???

I've seen in the monitor source "com_all_M16C.bat"

------------------------------------------------------------------------
cls
REM Generate one monitor for test purpose
REM call com_processor_M16C %1 %2 %3 %4 %5 %6 %7 %8 %9

REM Parameters:
REM %1: processor name, used only in the file name
REM %2: processor type

REM 0 - f(Xin)/2
REM 2 - f(Xin)/1
REM %8: Multiplier for PLL circuit. Only available with M16C/62P and M16C/6N4/6N5.
REM If PLL is not used this parameter must be set to 1.
REM %9: optional addition to indicate processors running with f(Xin) as SIO clock,

the 62P seems to be an other flash type (HND2-type)

Have your also tried the new KD30. It does flash the monitor automatically in the M16C when no monitor is inside.

Sorry I don't speak spanish
Maybe the next challenge when I've learnt english right ;-()

interrupt für kd30

Hi Gomez,

I've recompiled the monitor also and same result. I've erased also the microcontroller flash after that I've tried the KD30 but it this situation always give me communication error, no monitor is loaded into the chip (I've tried to change the CNVss pin to Vcc and GND in several positions).

Thank you very much.
Your english is perfect for me.... But for you name I supposed you were spanish.

I send you the init files for my program, can you tell me if you observed something wrong.

Kindest regards

Hi lince

sorry I was some days away.
That sounds not good what you wrote.

Your files look ok for me. But are you sure your code starts at 0xD0000 or the expansion bit is set (PM13=1)?

Has you tried to set:

;---------------------------------------------------------------
; Far ROM data area
;---------------------------------------------------------------
.section rom_FE,ROMDATA
.org 0D0000H


Maybe the KD30 cant't find your code because the sector from 0xC0000 to 0xD0000 isn't free at start yet. Look at your .x30 file with the Map-Viewer. Which code is in this area (main??)? Where is your interrupt section?

Thank you Gomez, I'll take a look at this and will keep you informed.

Kindest regards
