Bringing up custom board with MKM34Z128CLL5 - software support

[sivanesanr]

Hello,

I am designing a small electrical sensor based device with Freescale micro controller MKM34Z128CLL5 and new to bringing up microcontroller.

Have gone through some the links provided in the Freescale web site.I need some clarification regarding software part.

Is Code Warrior (Development tool) and OpenSDA (as debugger) are enough ?

If so, Is CW having some reference code to bring up the specified micro controller ?

What about OS, device drivers ?

Please help me to proceed. I know that I have put a set of generic questions.

If you need any specific inputs from me please as

Hi,

If customer is using TWR-KM34Z50M boardd? If yes, CodeWarrior MCU V10.6 and OpenSDA(debugger)  is enough for the development.

Customer can download KM34 CodeWarrior example project from below link:

http://cache.freescale.com/files/32bit/software/TWR-KM34_DEMO_SW.zip

About RTOS, customer can consider to use MQX Lite, which is embedded in Processor Expert software (as a component).

CodeWarrior MCU v10.6 also with Processor Expert software.

Wish it helps.
best regards
Ma Hui

Hi Ma Hui,

Thanks for your reply.

I will go through the project that you have suggested.

It is a custom board. we are not using TWR-KM34Z50M. This custom board has 1 LCD display and a electrical sensor chip.

We are using MKM34Z128CLL5.

Basically I need to configure this LCD display and the electrical sensor chip.

As I am very new to Micro controllers I need to understand the below things.

My questions are (May silly, but pls help me to understand),

1. Do I need to write code to bring up the micro controller ? (Hope I don't need to write. This micro controller have some software internally to start)

2. I may need to write like a device driver stuff to configure the external devices (LCD and the electrical sensor) right ?

3. Is MQX Lite RTOS software need any code modification to support  the chip MKM34Z128CLL5 / it requires some configurations ?

4. For debugging this board is still OpenSDA is enough or do you have a better suggestion ?

thanks for your help again.

Regards,

Sivanesan R.

1. Do I need to write code to bring up the micro controller ? (Hope I don't need to write. This micro controller have some software internally to start)

TS: The flash need be programed with customer application code. The flash memory is empty when chip shipped.

2. I may need to write like a device driver stuff to configure the external devices (LCD and the electrical sensor) right ?

TS: Yes, the LCD driver could refer TWR-KM34Z50M LCD demo and the sensor need to check which communication module using SPI/I2C, there already with SPI and I2C driver.

3. Is MQX Lite RTOS software need any code modification to support  the chip MKM34Z128CLL5 / it requires some configurations ?

TS: There with configuration options as PE component.

4. For debugging this board is still OpenSDA is enough or do you have a better suggestion ?

TS: In general, customer could select to use P&E Multilink Universal or Segger J-Link debugger tool.

More detailed info, please check below link:

http://www.segger.com/jlink-debug-probes.html

While, customer also could consider to use OpenSDA, as general debug application, that will be suitable.

Wish it helps.

Hi Ma Hui,

Thanks for your answers and suggestions.

From your answers I have got a good understanding.

Hi Ma Hui,

Need one more clarification.

Will Segger's J-Link base work with Code warrior without any additional software ?

Or do I need buy any additional software from them to make the J-link base work with CW.

Regards,

CodeWarrior comes installed with all the needed Segger software and drivers, so you can use a Segger J-Link out of the box.

Some Segger units can have extra add-on features and licenses (like unlimited FLASH breakpoints), but this is handled directly by the Segger software.

You can downoad the latest Segger software/drivers from the Segger web site, and it will detect your CodeWarrior installation and update it as necessary.

Thank you Ma Hui and Erich !

Maybe you need to download J-Link driver from below link, I am not quite sure if CW already provides J-Link driver.

SEGGER - The Embedded Experts - Software

After J-Link driver installed, there no need other software any more.

Wish it helps.
