We are using MBD with NXP demo boards such as S32K144. In further steps, we will not use NXP demo boards but use our own PCB boards that include NXP microprocessor. We are looking for how we can load our generated code to the NXP processor that is located in our own PCB. It seems that there is two ways.
The preferred one by we is changing Matlab Preference/Settings and connecting NXP on PCB with a JTAG tool and being able to install directly Matlab "Build" button. In this option, we would like to know how preference and settings should be selected? What JTAG we may be use ? Is there any prefferred JTAG ?
Second option is that Matlab generates C Code, and we install generated C code to NXP in PCB by using some Program such as S32Design Studio for ARM or sth else. In this option, what may be used for program to install generated code to NXP? What JTAG tool we can use?
Hello @ykarata1 ,
Currently, the MBDT toolbox provides only two ways of flashing the MBDT generated code: OpenSDA and Serial. The Serial represents the less expensive method to flash the board on your custom code. Because on the custom code, you will only place a header that connects to the UART signals (RX and TX) and the reset signal. The USB to Serial chip can be placed on another board.
The first scenario you proposed, where a third option should be available in our toolbox (JTAG), is not currently available. So you cannot flash directly from our toolbox via JTAG/SWD protocol. I think you can open a request for that.
The second scenario you proposed, requires to flash the generated code (elf file) using S32 Design Studio on your custom board. Any JTAG tool that appears in the drop-down list from the S32DS should do the job.
Just to give you a name, we use the Multilink probes. http://www.pemicro.com/products/product_viewDetails.cfm?product_id=15320168&productTab=1
Another way is to use an S32K144 EVB's OpenSDA as a debugger, via the SWD protocol. There is a header on the board that allows you to connect to an external MCU. We had an interesting discussion here last year, where one of our customers used an S32K144EVB board to flash his own custom PCB, https://community.nxp.com/t5/NXP-Model-Based-Design-Tools/Model-Based-Design-Tool-on-custom-pcb/m-p/...
Hope this helps,
