Which compiler did you use for compiling the ARM Sources?

So far I have been using Tasking compiler but I'm planning to switch to Yagarto as it's free and a good complement of the open source idea.

How much free space has the ARM Flash Rom?

The current firmware occupies 45 KB of the total 256 KB.

Is it possible to debug the code with the usb port on the ARM board?

You need a JTAG interface to do a true on-chip debugging. You can use the USB port with appropriate embedded software as a serial port.

The Tasking compiler has no makefile ? I tried to compile the sources with Yatargo, it works after some changes but linking is a problem because the startup code.
It seems i have to wait until you have ported the code.
Afaik Mikes Arcade Board has also an ARM CPU so that experiences with Yartago not only for the minimig board.

That means there is enough space to develop menu driven starter to select different cores.

Found such thing on ebay from a chinese seller.

Here is another spectrum core with a board is nearly similar to minimig. Ok. Another FPGA and another ARM Cpu and SDRAM.

Man.. this is awesome. I'll give it a try when time allows. I was wondering what it would take to include debuggers and assemblers to this set making it as an all-in-one developments system without any SD swapping or delays when switching between views (speccy, dev monitor etc)? I would love to have an ability to e.g. tweak my Z80 code timings with a monitor when the actual speccy code runs behind ;) Would ARM controller allow me to code such stuff easily (being familiar with ARM..)?

Hi Dirk,

how about the sources of this core and possible 15KHz function? :)

Bump

Is development on this core still alive? As I would love to use my mimimig to play spectrum games :-)

In the meantime i get a jtag interface for ARM CPUs.
The Minimig ARM Board has a 6/8 pin connector on its top side.
Is this the JTAG Connector ?
Is a pin description available, or much better a schematic of the ARM Board ?

Some of the JTAG signale are directly connected to 3v3 and can not be used.
I guess your mentioned pin connector is for TEST and ERASE line. On most ARM controller boards there are dip switches installed.

Thanks. So it will not be possible to debug with jtag interface on the arm controller board.
