Mf4.2 + gcc +stm32

Errol is the man. A challenge is always fun

GMod_Errol · November 12, 2011, 10:23am

Heheh, my ST32F4 discovery kit arrives on Monday(cross fingers) or Tuesday. That is why I finally started playing with the PK.

Some people might have started playing with the PK just to be eligible for Hydra, but not me… ;D

GMod_Errol · November 14, 2011, 9:05am

What the hell!!??

GCC defines int32_t as:

typedef signed long int32_t;

tinyhal_types.h defines UINT32 as:

typedef unsigned int       UINT32;

They are not the same.

GMod_Errol · November 15, 2011, 6:15am

Ok, so I’m assuming that I’m beyond help…

Anyway. Now ld.exe can’t find the libs that was compiled. Get this output:

Are you sure you have the correct parameters and path for gcc ? Maybe including some directories on PATH would help. I’m receiving my discovery kit today and will be playing with it when I have time.

GMod_Errol · November 15, 2011, 7:52am

Path where libs should be found is included on the command line.

Yeah, fun, isn’t it…

Gus_Issa · November 15, 2011, 7:55am

Ok this is very interesting and you seem serious about this so let me help

Have you tried compiling the imxs project like I suggested in my porting book? No errors? all is good?

GMod_Errol · November 15, 2011, 8:31am

I did, and it worked, with the old gcc tool-chain.

But the old tool chain doesn’t have cortex-m4. So I upgraded to the latest tool chain. Had to fix up a bit of crap in core files, but got it to compile.

Tried to compile imxs with new tool chain. Also bombs on link phase.

Now reverted to old tool chain. Must fix mcpu core again etc. Will report back now…

Edit: Just to clarify. iMXS now compiles with 26 odd warnings… STM32 still stuck at link stage…

GMod_Errol · November 15, 2011, 8:36am

Cool. Compiled for cortex-m3.

Down to one error:

Edit:
Nope. This linker just dies on the first file that it can’t find, unlike the newer one that looks for all files…
I have even edited the gcc tool settings file to put the path in front of every lib file, but then the command won’t execute in dos as the command line is 9000 chars long…

Gus_Issa · November 15, 2011, 9:52am

Do not use M4, keep on using M3. They are (almost) the same as far as NETMF code is concerned anyways.

… but I see you have already switched to M3 and it compiled.

Gus_Issa · November 15, 2011, 9:53am

The more you change the harder it gets. Do not try to patch things, instead, find the source of the problem and fix.

GMod_Errol · November 15, 2011, 10:13am

rolled back all core changes, including tool script changes.

I now get

I have traced this to the Cortex-M3 is thumb only. The command line for the gcc is missing an -mthumb flag… Where should I add that?

Gus_Issa · November 15, 2011, 10:17am

It can be in one of the script files or in the project “*.settings” file. I think it can be added wither way.

We know this compiles on MDK so there has to be an option you can copy.

Also, the solution “C:\MicroFrameworkPK_v4_2\Solutions\iMXS_thumb” is built in thumb mode so you can see how it is done.

GMod_Errol · November 15, 2011, 10:34am

In the STM32.settings there is this:
INSTRUCTION_SET>thumb2</INSTRUCTION_SET>

That works for MDK, but for GCC it must be without the “2” ie:
INSTRUCTION_SET>thumb</INSTRUCTION_SET>

It runs further, but still crashes on “Not Arm”:

I suspect that GCC has never been used for Cortex CPUs…

iMX_thumb compiles, but it’s CPU does support not Thumb mode…

Pablo · November 15, 2011, 10:37am

The last line:

Is referencing ARM9 Bootstrap and it shouldnt I think…

Gus_Issa · November 15, 2011, 10:42am

Yes, but you have narrowed it down to the known problem.

Look at C:\MicroFrameworkPK_v4_1\tools\Targets\Microsoft.Spot.system.gcc.targets

Gus_Issa · November 15, 2011, 10:43am

Yes correct.

Pablo · November 15, 2011, 10:56am

This should be called “Comunity Compilation”

GMod_Errol · November 15, 2011, 11:23am

I changed in Microsoft.Spot.system.gcc.targets:
From:

To:

From:

To:

[quote]<CC_CPP_COMMON_FLAGS Condition=“‘$(INSTRUCTION_SET)’==‘thumb2’” >$(CC_CPP_COMMON_FLAGS) -DCOMPILE_THUMB2 -mthumb </CC_CPP_COMMON_FLAGS>
[/quote]

After that I can change the instruction set back to thumb2 and get a lot further…

Now I get:

[quote]D:\MF\client_v4_2_comm\DeviceCode\Targets\Native\STM32\DeviceCode\STM32_Time\STM
32_Time_functions.cpp:176: error: integer constant is too large for ‘long’ type[/quote]

The line is:


static UINT64 g_nextEvent;   // tick time of next event to be scheduled
g_nextEvent = 0xFFFFFFFFFFFF; // never

UINT64 is typedefed as

typedef unsigned long long int UINT64;

GMod_Errol · November 16, 2011, 4:54am

The error was related to 0xFFFFFFFFFFFF being to big for and int, doesn’t matter that you are putting it in a long long.
Replaced with this, now it works:

#ifdef __GNUC__
    g_nextEvent = 0xFFFFFFFFFFFFLL; // never
 #else
    g_nextEvent = 0xFFFFFFFFFFFF; // never
 #endif

On too next error.
