[Embedded Master] Upgraded tiny booter, system is dead


#1

I dusted of my old Embedded Master Dev. Sys. 2.3.

I downloaded the latest SDK from GHI and microsoft (4.1) I tried loading my old app using VS2010 but I appear my firmware was old. So I tried loading the latest firmware for EMX from:C:\Program Files (x86)\GHI Electronics\GHI NETMF v4.1 SDK\EMX\Firmware
But this failed. So I updated my tiny booter. Using: C:\Program Files (x86)\GHI Electronics\GHI NETMF v4.1 SDK\EMX\Firmware\TinyBooter
Some relevant output from tera term:
1.08
BL
Start File Transfer
CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC
File Transfer Finished Successfully

After update I tried to request the verion but the system did not respond any more. Then I reseted the system and the display got blank. Now I cannot enter the clr of boot loader any more. Leaving me with a board that I cannot use :frowning:

What did I do wrong? And how do I get it working again?


#2

New firmware defaults to USB so once you are done loading tinybooter, switch the USB cable to the other connector.

You need to use power supply to power the board.


#3

Just tried that.
Seems to work. Loaded new clr, system appears ok now.
But the display does not work any moreā€¦ Do I need some configuration for that?


#4

deploying of applications works ok now. But the manual does say anything about the display of the EM


#5

Is it the non TFT display? Those are no longer supported


#6

Can I drive from clr? Did anybody port it to c#?


#7

Yes you can. It is an spi display.
