FEZ Portal Display system.OutofMemeoryException

TinyCLR OS
1

I have tried to load the FEZ Portal Official demo into my FEZ Portal and when it runs I get an “An unhandled exception of type ‘System.OutOfMemoryException’ occurred in GHIElectronics.TinyCLR.Devices.Display.dll” when setting up the display controller.

I have also tried Greg Norris’s teleprompter program as it is quite concise but it also generates the same exception.

I have tried the usual erase program + firmware and reload firmware with no luck.

Running VS2022 V17.11.4 with Extension TinyCLR OS Project 2.3.0.1000
All nuget packages are 2.3.0.1000
Portal is running firmware 2.3.0.1000

Any thoughts as to where I am going wrong - minimal program below.

Extend memories. You can read here
https://docs.ghielectronics.com/software/tinyclr/tutorials/external-memory.html

but the config tool let’s you do that easily.

Thanks for pointing me in the right direction @Gus_Issa :slightly_smiling_face:

It seems like I have a faulty FEZ Portal - if I :
Connect with TinyCLR config
Erase all
Update Firmware
Power cycle board
Connect with TinyCLR config (SC20260)
Enable “Extended Heap” and “Apply” (Popup "New config has been applied …)
Portal now only appears as “Com4 (GHIElectronics)” in TinyclrConfig.
If I cycle the power to the board it does not appear at all in TinyClrConfig - requires putting into loader mode to allow connection and reload of firmware.

I tried the above process on a SCM20269D Dev and it works exactly as it should so my thiking is there that there is something amiss in the external ram.

You are probably right. Do you see anything visually wrong with the module?

The module, too my untrained eye, looks to be in good shape.
