Whats does
Debug.WriteLine("Used: " + Memory.UsedBytes + " Free: " + Memory.FreeBytes);
Give you.
var freeRam = GHIElectronics.TinyCLR.Native.Memory.FreeBytes;
var usedRam = GHIElectronics.TinyCLR.Native.Memory.UsedBytes;
Debug.WriteLine("free Ram : " + freeRam.ToString() + " - used Ram : " + usedRam.ToString());

Your still missing some ram…
I will email you.
Hi Justin,
I’ve tried your last firmware (you sended it to me via email) and it worked well with enough memory for my project. If you are able to free more memory let me (us) know!.
Thank you.
hmmm I must have v1.0 device too… How do you tell difference?
Does it say v1.1 to the left of the USB connector?

1.0 have 8 Mhz vs 1.1 have 12 Mhz
lol thought you might say something like that! Could not see anything in the lighting I had.
But took it down to the workshop and yeah can see it now v1.0
My eyes are getting worse!
Apologies!
After downloading GCC/CMSIS (https://docs.ghielectronics.com/software/tinyclr/native/porting.html)
Build for Electron11
Include #define STM32F4_EXT_CRYSTAL_CLOCK_HZ 8000000 to Device.h
Setting approp Vender ID and ProductID
Building .DFU with DfuSe from HEX, deploying OK
Im still getting Unknown USB Device
Or using any firmware .dfu’s above getting very low free ram.
Still confused about what is needed to get latest firmware that works well… Getting late. Tired
Give this a crack - totally untested 
https://store.ingenuitymicro.com/Content/Images/uploaded/firmware/ElectronV1_TinyCLR.zip
Make sure that the below is 5 and not higher as that gobbles ram.
#define DEVICE_MEMORY_PROFILE_FACTOR 5
Also, the scatter file for Electron in GIT is suboptimal…as the values are based on a G30 so missing 32k ram.

Thankyou appreciated!! That seems good!
Fixed “Unknown Device” and ram issue
free Ram : 51504 - used Ram : 38848
Still baffled at what causes the “USB Unknown device”, I am setting the USB Vendor ID and Product ID correctly as per GHI, and also as I have a v1.0 did the #define STM32F4_EXT_CRYSTAL_CLOCK_HZ 8000000 to Device.h
Email me your project files and I will do a diff for a giggle and see what’s different.
Have you defined DEBUGGER_FORCE_API and DEBUGGER_FORCE_INDEX in device.h for some reason?
There’s a bug in the GHI code that prevent initialization of the pointer to USB config struct.

Hi Justin
Has there been any newer TinyCLR ports for the Electron?
Cheers
Paul
Are you an insider by any chance?
umm, no, bugger…
#1 fact you need to realise: TinyCLR OS 2.x and beyond is not going on older devices, it is only for new processor capabilities. And TinyCLR OS 1.0 is an interim step that is now no longer developed - so it’s unlikely that there’s been any effort spent by anyone in the community building out capabilities here.

I am currently focusing on SITCore…

Yep realise that, just have it here and have a application for it because of its small size.
And saw it on Justin’s site, so was just out of interest
