Hi, I am looking for some cheap and faster programmer and debug for these microcontrollers throught USB. Can you recommand me something? Thank you.
We've an USBtap interface.
I recommend you to contact your Freescale distributor for more details.
The web documentation is temporary not available.
Please have a look for details
Thank you for tip.
Will I able to use freemaster with this programmer?
Yes but if you're using Processor Expert only the SCI connection is available for the moment via the PC Master bean.
PC Master was the previous version of Freemaster.
I found some interresting information to use Freemaster via USB connection instead of SCI port.
Now the question are:
- do you want to use the PC Master bean via Processor Expert ?
- do you have a SCI port on board and on your PC ?
I don´t use Procesor expert. I thought I can use freemaster throught JTAG, is it possible? Or only throught SCI? Else I dont have SCI communication in NB, I would have to use USB-SCI converter.
The Freemaster can be used with the JTAG.
A colleague will create a FAQ to explain how to use FreeMaster and USBTap via JTag.
I will keep you informed.
Is there a link to this FAQ?
It appears the FAQ is not public at this time.
See below the info:
First, you need FreeMASTER 1.3 or newer version, and FMASTERSCIDRV installed.You can download FMASTERSCIDRV here:fmaster_scidrv_11beta.ZIPThe PC_Master bean supplied by Processor Expert only supports the communication via SCI. If use JTAG interface, we have to add some code in project for JTAG Communication between FreeMASTER and the target board.Please see the example project:Example ProjectThe source files under \SCIDRV subfolder contain the code for the FreeMASTER driver. This project uses Interrupt vector Beans to define FMSTR_Isr as EOnCE TX/RX interrupts. use Init_ADC Bean for simple sampling ADC channel 0. Sampled value can be displayed in FreeMASTER. Please refer to freemaster_cfg.h file for necessary definitions for FreeMASTER driver.In the FreeMASTER tool , please select the ELF file and communication type in Project Options Window. To open it, please click on 'Project' menu, and select 'Options'.On the 'Options' Window, please click on the 'MAP Files' tab. On this panel, use the first button to browse the folder and choose your ELF file.The communication type is selected under 'Comm' tab, see the attached screenshot:Project Options1) If communicate with USBTAP, please enable 'Plug-in Module', and select 'FreeMASTER CodeWarrior-CCS JTAG/OnCE Communication Plugin'.CCS server must be running with FreeMASTER together, and its communication port should be set as USBTAP.2) If communicate with Parallel-> JTAG interface, please enable 'Plug-in Module', and select 'FreeMASTER 56F8xxx Direct-LPT JTAG Communication Plugin'.CCS server need not be active. Please exit CCS when FreeMASTER works via LPT->JTAG interface.
