Today i was thinking about to begin again with .net microframework.
The last months i was very busy with travels, offers and work. But today i continue my work with the tahoe board witch i bought last year.
I want to write a small tutorial to begin code, and my objetive is develop a small control semaphore system.
First of all, i need to upgrade the tahoe firmware to the new release. I want to share my experience with you. Take care with the Firmware keys.
You need to use MFDeploy to change the keys of the tahoe bootloader to can install applications, because it's there is a key in the bootloader if you don't use the key you can install any application.
I upgrade the firmware but when the installer was in the application deploy phase it fails and it can not access to de Flash memory, in the tahoe screen prints the error "signature fails".
This issue was my first problem but thanks to Martin wellford to publish the solution in his blog.
Y use mfdeploy to upgrade to keys in the tahoe to a empty key pair set.
When i upgrade the keys i begin again to upgrade the firmware and the process finish correct.
I see again the Device solutions logo ;)
Regards. The next post i will write about my first tutorial solution. I think to do a small semaphore systems.
