KDS Register View

[Toe]

Does KDS have a view that shows all of the registers in the MCU like CodeWarrior?  The register tab in the debug perspective only shows "General Registers", I find that the GPIO/ADC/etc registers are helpful when getting a new piece of code that isn't working properly up and running.  Is this implemented under a setting that I've missed?

I'm using a K22MX256 on a custom board right now.  It's not a huge deal, but I would be interested if you're willing to write something up!  I have a few of those FRDM boards as well (K20 and KE02 and one more it seems I've misplaced).

Thanks for the reply.

Hi Ryan,

are you sure this is a K22M device? K22FN? K22FX? K22DX? K22DN?

Guess it's good you asked because I told you wrong.  It's a MK22DX256.  My apologies, not sure where that initial part came from!

Ok, that makes sense now :-)

I have described the steps how to install the plugin (plus the needed patch for Kinetis devices) here:

Let me know what you think.

Best regards,

Hello Erich,

The K64 seems to be implementing Data Watchpoint and Trace (DWT) unit. Would it be possible to add DWT registers to the EmbSys Registers view? I would find DWT_CYCCNT quite handy.

Hi Piotr,

yes, that would be possible. But so far ARM indicates that the core peripherals (like NVIC, etc) shall not be part of the CMSIS-SVD files, so they are missing in the files provided by Freescale (and other vendors).

But nothing should prevent to have those added to the XML files.

Hi Erich,

XML file shouldn't be to difficult to modify. Would you know of any document describing expected structure of this file?

Hi Piotr,

That's pretty simple to install, thanks for putting together such a thorough guide!  Doesn't look like my exact chip is supported, though.  It has a MK22F12 which, like most Kinetis parts, has similar registers.  There are some awkward places that may be due to the part not being correct or not completely supported:

There should be 32 pin control registers for port B, but it only shows the first one.  The location is correct, though.

There are a few other instances similar to this, but overall it is quite useful and better than the default register view.

Thanks again for this and all the other work you do on your mcuoneclipse blog.

I have implemented last night initial support for %s (CMSIS-SVD dimElementGroup). Anyone interested to try it out?

[Toe]

Absolutely, I'll try it out.

[BlackNight]

attached is an updated plugin (replace your current plugin with it).

I try to publish a short write-up in the blog tonight if I find time.

I have put up the full package now: EmbSys Registers View with CMSIS-SVD dimElementGroup | MCU on Eclipse

[BlackNight]

Yes, these items with the %s only show the first register. There is a problem in this register view because the %s items are 'array of register' items, and they are not handled correctly yet.

Need to see if and how this can be improved in the plugin, as not all aspects of CMSIS-SVD are handled yet.
