I got my FRDM-K82F a few days ago and it is a very interesting piece of hardware. I played with the demo that uses the accelerometer to light up the RGB LED based on the data a few times. This I did by pluggin in to a USB host as well as just a 5V USB charger. All the time I used the SDAin port. After a few times doing this, I lost the mass storage device named EMBED that was 1MB of memory space I believe. After that I read some and learned to reset into bootloader mode (unplug board, hold reset, plug in board, and release reset). This does give me a BOOTLOADER drive in windows, but it only has 100kb of storage space. Also there are no files such as 'last.txt' or 'fail.txt' present on the drive. I loaded a PEMicro Serial Driver onto the BOOTLOADER drive, and then pulled the cable out and replugged. The board does not show any MSD but it does produce a come port at COM6. I tried to connect at 115200 as shown in some guides, but never got anything. I know I am a newb, Arduino was as faras I had gone before. But, did I fry something? I cdo have the MSD_DEBUG_PEMicro_1.08_SDAV2.SDA file but it is too large to fit in the 100kB BOOTLOADER drive. It is too big by more than double. What is going on? I do get that the board has a K20 chip for programming, and I can see that on EMBED online site, but I never can see the FRDM-K82F chip there. I did install SDK, and several drivers, and KDS3, but all I can see is that I do have the package for my K82F installed in KDS, but no success with compiling and downloading to board. Where did my MSD (mass storage device) go, for the K82F chip? How do I fix this if possible? Again, sorry about the newb-ness quality of this post, but this is where I am with it. Thanks,

What I have tried:

See above sorry.

What about asking a forum of users or the maker ?

It's very unlikely you're going to get an answer to your question here. Sure, there are some people who do microcontroller stuff around here, but not a lot.

Your better bet would be to find a forum dedicated to the hardware you're using. There you're going to find a ton of users who have experience on the hardware and maybe have had similar problems.

Such as here[^].

I understand, but when I did search for a very specific string I was directed here to a guide about Code Warrior and Freedom MCU's. If that fellow would post his 2 cents maybe I could solve this. Looks like there is a way to increase memory available to bootloader but I did not ever decrease it so... There are crypto features in this MCU and I have not dealt with that much before. Guess I will be learning some new shiz for this K82F. Floating pt unit, 32Mb NAND flash and all kinds of speedy interfaces it seemed like a winner but if it this far over my skillset I will be studying a while it seems. Thanks anyway.

First, you posted this as a solution to your own problem. DON'T. There's a "Have a Question or Comment" button. Use it. That way, the person you're trying to talk to gets notified you said something. Since you posted this as a solution, I didn't get a notification. I found your post just be stumbling upon it.

If you're thinking that one certain person is going to see your post, you're going to be waiting for a VERY long time. The chances of that happening are close to zero.

If you've got a link to an article here someone wrote about "Code Warrior and Freedon MCU's", look at the bottom of the article and you'll find a forum dedicated to it. Put your question in there and you've got a better chance of getting a response. Articles are supported by the people who wrote them, not by the entire CodeProject site.

If the person is still around, they'll get an email saying that you posted something in that forum. If the person reply's, great! If not, you're going to have to use the forum I linked to before.
