T1042 Flash Programming

[faizmajeed]

HI!

I am using T1042 processor and making a custom board using reference design board. I want to boot my board from NOR flash. for this purpose i have to place boot-loader in NOR Flash. Now please suggest me some idea to program NOR flash externally. what software can i use and what protocol should i use for this purpose i.e Ethernet , Uart or any other.

Thank You

The recommended way is to use our CodeWarrior software and CodeWarrior TAP debug probe to program U-boot boot loader to NOR flash. After that, you can use U-boot to load Linux kernel over Ethernet and program it to NOR flash.

Have a great day,

In my processor there are only 5 pins for JTAG but your CodeWarrior TAP debug prob contain many pins on dubug header. Please specify any connector if i needed between my processro JTAG port and your prob debug header. because i want to program my flash through my JTAG conector using your CodeWarrior TAP prob.

Thank You

I'm not sure what you mean by "your processor", in case if you mean our T1042 processor, than it should have standard 14-pin JTAG/COP header, connected as specified in our documentation. Please look T1040 family Design Checklist (application note AN4825), Figure 25.
