can't connect to my netduino anymore

Hello, I need someone's help on this. I tried updating to the 4.2 rc4 firmware and ran into an issue. I first jumpered the 3.3v to the little copper tab by port 0, then i tried connecting the device and windows said it couldn't connect to it and eventually figured out that it was a gps camera. Well, I was able to use SAM-BA to load the tinybootloader unto it, but now i am trying to get it to show up in mfdeploy and it only shows up under serial connections com3, but of course can't ping/erase/upload to it. What else can i do to get the card back into operation? Thanks, Viktor.

ok, got it figured out, remembered i could just uninstall the device from device manager and do the detection again. This time it was found as the right device.

Ok, i was able to flash it with 4.2 rc4, and i am getting response when i ping it in mfdeploy, and i have just a power LED on until I try and load a project into it, then both led's come on and i'm not getting any feedback from it. Visual Studio is not able to go into debug either. Anyone?

Hi Victor, Did you only update the TinyBooterDecompressor.bin or also the ER_FLASH file?

Hi Victor,

Did you only update the TinyBooterDecompressor.bin or also the ER_FLASH file?

I was able to update the ER_FLASH and config, the board seems to have good vital signs after this until I try to load a project unto it then I get both lights on.

Here are the procedures I've done a few times:

1. Erase by doing the copper tab + 3.3v
2. use SAM-BA to clear flash (just to be sure), then load tinybootloader
3. disconnect/reconnect it, then go into mfdeploy and load the FLASH and CONFIG
4. disconnect/reconnect, ping returns TinyCLR, then go into network config and do the settings there.
5. power LED on, onboardLED off.
6. Try to start a project after I upgraded it to 4.2 and it gets built and when its trying to reboot the card I get both LEDs to come on and debug never kicks in. Also the card wont respond to a ping then.

Thanks,
Viktor.

Hi viktor, What are you trying to do in your app? Is there an SD card inserted? What happens if you remove it? Chris

Hi viktor,

No sd card. But I just re-installed the Netduino SDK 4.2 and now its taking the projects. Thanks again for chiming in.

Got it...

Wrong version of the Netduino SDK (4.1 instead of 4.2).

now it all works

I've installed the right version mf sdk(4.2) and netduino sdk(4.2), but my device failed to give any response now. How can I resolve this problem?

Can you give us more details on how you updated your Netduino, what it shows up as in Device Manager, etc.?

Maybe not, but I can try to jump in!
I am able to successfully deploy the tinybooterdecompressor.

Afterwards, the netduino will not enumerate over USB. I have verified that the tinybooterdecompressor is programmed to 0x100000. I must be missing a step because after a power cycle, the device has the tinybooterdecompressor but I can not access it in mfdeploy. (it isn't avail over USB and pinging over serial yields no response)

I am using a usb->serial converter to do the flash erases/programming. I have tried multiple versions of the tinybooterdecompressor.

FWIW sam-ba 2.8 works for me under compat mode. (I am W7 64 bit) I have Micro SDK 4.1 and 4.2


[this is not a + device. -- I need the latest beta firmware for I2C internal addressing. I have an AVR-ISP if that helps.]

Didn´t you forgot to set it to boot from flash in SAM-BA (on the scripts combobox), before the power cycle? Idk how it may helps, but there are a new version of SAM-BA (v2.11) too.
