problem using FRDM-KL25Z or FRDM-KL05Z with Keil MDK

I downloaded Keil uVision4 and exported my KL05Z project to Keil. My problem is that Keil 4.74 does not seem to have the mbed cmsis-dap driver needed to download code to flash. Somehow I do have it working on one PC, but can't remember how I got it working. I seem to recall neeeding an obscure driver. I also remember I never got uVision5 working.

Thanks, Tom

I remember something like this, although for uVision 5. The problem now is it would mean you need an installer, which was hosted in the past on the Keil site, but not anymore sadly: https://developer.mbed.org/users/Sissors/notebook/unbricking-kl25z-after-setting-reset-pins-as-gpio/

So the issue now is getting that mdkcm500. I also looked quickly where it seems to be getting my flash drivers now from in keil, and you can try downloading the packs here: http://www.keil.com/dd2/pack/

That is the file that I was thinking of. It turns out that you don't need it with uVision4. What you do need is to install the winserial drivers. I did not think this was needed unless you were using virtual com, but once I installed it, uVision4 started working.

Thanks, Tom
