Re: STM32 target practicability question

I now have code loading onto the maple mini using its built in USB DFU bootloader and have the led flashing and the clock and PLL initialised.

When I have the debug uart working too I'll post the files.

Re: STM32 target practicability question

I've got the EZSBC2 Blinker example running now after correcting the errors in NXP's load script.

I've tried changing the speed and commenting out SetupPLL() in Main, after which everything blinks quite a bit more slowly, so I know what to expect now when starting with the STM32F103.

Re: STM32 target practicability question

That looks very good and looks like it should cater for pretty much any M3 processor. Thank you. Is the heap address range constrained to be within the data address range? I thought I remembered somewhere in your documentation that it isn't so that alternate on or off chip memory can be used for the...

Re: STM32 target practicability question

That all sound great - thanks.

I have an Ezsbc2 already on order and can get hold of the STM Discovery kit quickly if I run into a problem.

Re: STM32 target practicability question

I realise I forgot to mention - though this may be normal or obvious - that the Maple Mini bootloader, although loading at 0x0800 5000 does not use a different flash image layout to what you would load with JTAG at 0x0800 0000, it is still expecting a vector table followed by code. After loading the...

Re: STM32 target practicability question

Hi. I've been going through Astrobe sample code and documentation to try and understand it and see what I'll need to do for the STM32F103. Here are my thoughts and questions comparing to the LPC1343. Obviously I'll need an all new MCU module. Is anything in this referenced by the linker generated st...

Re: STM32 target practicability question

Thanks. I just placed my order for the professional edition for the Cortex M3.

I'll see how I get on with that first.

Re: STM32 target practicability question

Thanks for your answers and patience. By coroutines I meant something like the Modula 2 couroutines module http://www.modula2.org/reference/isomodules/isomodule.php?file=COROUTIN.DEF to enable simple task switching to be implemented. I want to be able to implement the simplest prioritised multi-task...

Re: STM32 target practicability question

Hello again, I have a few more questions to make sure I have everything I'll need if I go ahead. I mainly do dynamic control work and I'm wondering whether with Astrobe it will be easier for me to use an M4 processor from the outset. In C I have brewed my own fixed point arithmetic for the M3, but I...

Re: STM32 target practicability question

Great. Thanks for being willing to consider this.
I am away from tomorrow till the 10th of April and will be in touch shortly after that to buy the compiler and get started.
