re - download again firmware for TinyCLR Electron

The above firmware does indeed work but your not going to have much fun with it in the real world as the memory mapping is not quite right.

With a couple of changes…

Justin · August 3, 2019, 10:31pm

TinyCLR OS v1.0.1 for above is here

valon_hoti_gmail_com · August 4, 2019, 4:20am

with this firmware i’ve got usb unkown

also with source from DEV Branch
but with MASTER Branch seems it was ok , also if i install FEZCLR dfu and install from TinyCLR Config Setup v1.0.0

You have an Electron v1?

If so then that’s probably your issue as v1 had an 8 MHz stay vs 12 KHz for v1.1.

My download is set for 12 MHz

valon_hoti_gmail_com · August 4, 2019, 7:44am

yes the first Electron 1.0 not 1.1 i don’t know what problem have but i face two problems with this master piece

if i build with new dev branch tinyclr have this issues
if i build with old master branch tinyclr have no issues.

Add #define STM32F4_EXT_CRYSTAL_CLOCK_HZ 8000000 to Device.h

valon_hoti_gmail_com · August 4, 2019, 8:16am

Whats does

Debug.WriteLine("Used: " + Memory.UsedBytes + " Free: " + Memory.FreeBytes);

Give you.

valon_hoti_gmail_com · August 4, 2019, 8:30am

        var freeRam = GHIElectronics.TinyCLR.Native.Memory.FreeBytes;
        var usedRam = GHIElectronics.TinyCLR.Native.Memory.UsedBytes;

        Debug.WriteLine("free Ram : " + freeRam.ToString() + " - used Ram : " + usedRam.ToString());

free Ram : 41456 - used Ram : 39872

jango_jas · August 5, 2019, 1:23am

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.
