my mini ml128 board photoshot
SCI port cannot beed detected even I opened the power supply.
Let me know your email address, I can photo my whole development system to you.
Many thanks!
Let me know your idea for this freemaster D.O.A situation.

Hi,
Regarding the communication - the OSBDM/OSJTAG - CDC Serial Port driver is needed to connect the board via USB. The comm speed is 19200 Bd. This way, no additional USB-to-SCI converter is needed. For this case jumpers J6 and J8 are set for 1-2 connection. If you cannot find such driver on your computer, please visit PEmicro - P&E Microcomputer Systems: Over 30 years as an Industry leader in Embedded Systems Develop... and update your drivers.
If you are using your own USB-to-SCI converter, then you would probably connect via J7 connector, while the jumpers J6 and J8 would be configured to 2-3. Even then, the communication speed is 19200 Bd.
The error messages mentioning JavaScript may be caused by missing connection, however based on my experience it is caused mainly by old version of the MS Internet Explorer (I'm using version 11.1266.15063.0).
Even if the script error appears, you can click YES to continue.
And - if you would like to have the LED diode to indicate the status of the application, you would need to enable the J5 jumper. It is not critical to the application, however it is good to have it :smileyhappy:
Best regards
Matej
I did exactly according to what you mentioned above. However, I found OSBDM needs exact hardware driver.
Because the OSBDM in my win7 x64 control panel have warning flags. I do not it is a problem for correct connection.
And I searched the website and did not found any ML128 mini board hardware drivers for downloading.
What kind of driver you installed on your computer? PL232 usb to serial port driver only?
Let me know your NXP driver package download http link if you have.
Many Thanks!
I did exactly according to above you mentioned. And the yellow warning flags disappeared now.
The freemaster project could not detect the motherboard voltage.
And there is a mistake in the FOC control webpage.
System requires clear fault. My motor did roate for a while. But it never rotate again when clear fault appeared.
How to clear fault?
Do I need to modify my PMSM motor configuration parameters?
My current setting is below:
Let me know where I should modify my parameters or corresponding settings to make my DC motor rotate without any fault again.
Many Thanks!
Hi,
Maybe it is caused by me exporting the project to a zip file. Can you please go to the settings of the FreeMASTER project and check the following?
Even if the setting is the same (mainly the Default symbol file path), please click on the [ ... ] button and browse to your CodeWarrior project directory, FLASH folder and select the AN5327_SW_CW10.elf. Then click OK and test it again.

Hi Matej,
The above picture is my side configuration for freemaster.
I think there is no any problem with the configuration.
Maybe I need to change the cables for the motor because the mental line is too thin to load a very big current.
My another major problem is the SCI port.
I still could not connect my mini board with my usb to serial port cable.
According to we discussed previsouly, we configured J6 and J8 from 1-2 to 2-3 and then set the baud rate is 19200, then I check the usb serial port number is exact com4 in my hardware manager in local control panel.
But, when I connected my miniboard with the usb-serial port, it always shew no any board detected. I am doubt in your side, your serial port work good or not?
If yes, what is your configuration for usb2serial cable?
Many thanks!
Hi Matej,
I did add the instruction of active the internal oscillator into the program and compiled successfully. However, I found another trouble: the AN5327_PMSM_FOC_Sensorless_SingleShunt.pmp, which can not show the FOC motor control page completely. And it always show security alert msg which need people click "Yes" to continue it.
Furthermore, the freemaster cannot show the FOC motor web page at all as below picture:
How to solve this problem, so that I can debug my single shunt FOC motor project.
Many thanks.
I modified this code for the file named MC9S12ZVML128_PMSM.c because I found the demo project downloaded from
NXP official website use the external oscillator but not the internal one. And after reading the miniboard schematic I found the MCU chip of MC9S12ZVML128 use its own internal oscillator. And the external oscillator connected to a 8 bit MCU of NXP. Thus, it is necessary to modify the MC9S12ZVML128_PMSM.c file initcup() function to switch from NXP original external oscillator to the internal one.
The external oscillator for the 8 bit MCU for downloading purpose:
I added a defination instruction to the file named MC9S12ZVML128_PMSM.c:
#define _INTERNAL_CLOCK.
Also I modifed the source code for init the MCU of MC9S12ZVML
void initCPMU(void)
{
// Wait for stable supply after power up
while (GDUF_GLVLSF)
GDUF_GLVLSF = 1;
CPMUREFDIV_REFDIV = CPMU_REFDIV;
CPMUREFDIV_REFFRQ = CPMU_REFFRQ;
CPMUSYNR_SYNDIV = CPMU_SYNDIV;
CPMUSYNR_VCOFRQ = CPMU_VCOFRQ;
CPMUPOSTDIV_POSTDIV = CPMU_POSTDIV;
//#ifdef _EXTERNAL_CLOCK // I commented these 3 lines because ML128 Miniboard does not have external oscillator to use.
//CPMUOSC_OSCE = 1; //The original demo project named MC9S12ZVML128_PMSM does define CPMUOSC_OSCE, so that it always use external oscillator but in fact there is no external oscillator in the schematic.
while (CPMUIFLG_UPOSC == 0) {}; // Wait for oscillator to start up (UPOSC=1) and PLL to lock (LOCK=1)
//#endif
while (CPMUIFLG_LOCK == 0) {};
CPMURFLG = 0x60; //Clear PORF and LVRF
return;
}
I have no idea if this defination can make internal oscillator works or not.
After I modifed this source code of MC9S12ZVML128_PMSM.c in the demo project, I redownload it to MC9S12ZVML
However, I found the internal oscillator still does not work at all.
Please let me know if you have the exactly correct demo project for Mini ML128 board which can drive a single shunt resistor FOC motor.
Need your help, you are welcome to give demo projects for single foc motor or http links for single foc motor.
Many thanks!
The above Chinese JavaScript Error information means
The fileProcessing.js NO. 87 line and Char 6 "missing Object". I tried all of my computers, this kind error information all appeared when I run AN5327 dual shunt resistor project of freemaster.
My IE version are 8.0 9.0. I also open the original js file to look the js code of Line 87th as below:
The above pictures just for help you to understand the MCAT js file err information, which cannot show the motor tab corectly.
Thanks.
Hello,
I found NXP demo board for FOC motor are different. Single Shunt resistor circuit are very similar with double shunt resistor, but the code are obvious different. For example, ML128 mini board can drive not only BLDC motor but also single shunt FOC motor. However, when you need to drive FOC motor with two shunt resistors, you need to switch to AN5327 and the NXP demo project are obvious different.
Furthermore, I need to know if there is a demo source code to switch the external oscillator on the ML128 Mini Board to the ML128 MUC its own internal oscillator? For your better understanding this question, I attached an picture on this question.
Attached source code below also:
/*****************************************************************************

void initCPMU(void)
{
// Wait for stable supply after power up
while (GDUF_GLVLSF)
{
GDUF_GLVLSF = 1;
}
CPMUREFDIV_REFDIV = CPMU_REFDIV;
CPMUREFDIV_REFFRQ = CPMU_REFFRQ;
CPMUSYNR_SYNDIV = CPMU_SYNDIV;
CPMUSYNR_VCOFRQ = CPMU_VCOFRQ;
CPMUPOSTDIV_POSTDIV = CPMU_POSTDIV;
while (CPMUIFLG_LOCK == 0)
{
}
CPMURFLG = 0x60; //Clear PORF and LVRF
}
Wait for your reply and Many thanks.
