Flashing cortex M4 via USB/SM

[Naampie2000]

Hi,

I'm building a board around a cortex m4.And was wondering in what ways can the configuration file be loaded onto the board. "Say if I want it to behave like an arduino"

Since the JTAG connector is big compared to the board, and close to the clockpath. Can I flash it via USB or Smart media?

Kind regards,

Hi

What CortexM4 part do you use?

Normally for Cortex M4 LPC, we can use Jtag or SWD interface for debug or program during development stage.  SWD is 10 pin interface, which size is smaller than Jtag, here is design consideration

if we just program image ( not debug), we can check the specific device ISP programming interface. Most of the LPC cortex M4 part can support USB programming. Thus we need to check the part user manual,

Have a nice day,

Hi,

I'm opting for an Arm Cortex M4 MK66FX.

Online I was looking at tools like Atmel's Flip. Irc but could have been another software application that promises to do the same thing of flashing via USB.

For K66, our recommended tool is P&E Multlink Universal or standalone programmer Cyclopro

P&E also has PC side programmer for it,
