Using IAP application note with RVDK

Hi,

I want to try the AN2078 - STR7 In-Application Programming using UART, but the project was created with EWARM and I use RVDK. I searched on the forum but I didn't find a easy solution to convert EWARM projects to RVDK one. Is there a way to do that ? Or must I create a blank RVDK project and fight with the project setting to make it work?

Thanks in advance

Hi tumnao,

You can just use one example from the existing RVDK Examples library from

ST as a template and then just copy/paste the Appli Note main files. It should work smoothly :)

Thanks Rave and ibtiss for your quick replies. I tried different things like using the IAP v2 rvdk project with the IAP v3 sources files, or as Rave suggered a simple exemple in the library, but that didn't do the tricks.

Here is my last attempt step by step :

I copied

\str71xlibstd\examples\gpio to \str71xlibstd\examples\iap.

I added all theses file from the IAP rev3 :

71x_conf.h

7xx_flash.c

7xx_flash.h

common.c

common.h

download.c

flash_conf.h

flash_map.h

main.c

ymodem.c

ymodem.h

I added to project properties *COMPILE=arm/sources/files all the above .c files.

I added ibtiss modification to the scat file.

At compilation there was theses kind of errors :

''..\..\..\project\include\gpio.h'', line 62: Error: #20: identifier ''inline'' is undefined

inline u8 GPIO_BitRead(GPIO_TypeDef *GPIOx, u8 Port_Pin)

^

''..\..\..\project\include\gpio.h'', line 62: Error: #101: ''u8'' has already been declared in the current scope

inline u8 GPIO_BitRead(GPIO_TypeDef *GPIOx, u8 Port_Pin)

^

''..\..\..\project\include\gpio.h'', line 62: Error: #65: expected a '';''

inline u8 GPIO_BitRead(GPIO_TypeDef *GPIOx, u8 Port_Pin)

(..\..\.. refere to the str71xlibstd folder)

So I modified 71x_conf.h ''#define inline inline'' line to ''#define inline __inline'' as I saw that in others working 71x_conf.h.

I tried to recompile and get :

c:\progra~1\arm\rvct\programs\2.1\526\st\win_32~1\armlink --list Listing.txt --entry Reset_Handler --scatter ..\scat.scf --symbols --map DebugRel\ymodem.o DebugRel\download.o DebugRel\common.o DebugRel\7xx_flash.o DebugRel\main.o DebugRel\71x_lib.o DebugRel\retarget.o DebugRel\71x_vect.o DebugRel\71x_init.o -o DebugRel\gpio.axf

Error: L6630E: Invalid token start expected number or ( but found F at position 15 on line 34

Error: L6629E: Unmatched parentheses expecting ) but found F at position 15 on line 34

That make me think that I should also modify the entry point in the properties and what about the .s assembly files .... argh

In short I am totaly lost with project properties, scatter file and other such low level settings. For my main project, I managed to get it work but I didn't really understant what I done.

Is there a good documentation for beginners that I can read before asking stupid question ? :)

Ok, scatter file are more clear to me now (not completly, but more :) )

Now I think my problem come from the 71x_init.s and the 71x_vect.s. In the IAP v3 they are placed under the EWARM folder, and I think this is because they are compiler dependant. Is this correct ? Anyways RVDK complain about syntax like ''MODULE ?program_start'' and ''RSEG IRQ_STACK:DATA(2)''.

Anyone know RVDK and EWARM enough to explain me that ?

Ok I succeded in compiling the IAP v3 with RVDK...

So I had this idea before you send me the .s file ibtiss (Theses file was from the standard STR7 library, right ?) I just had to remove reference to all the IRQ handler has the IAP don't define them.

And by the way thank you for the scatter doc, it help me a lot.

But all that bring me some new questions :

1) Now the IAP work on my str7 eval board (MB393), but if I want to use it on my own hardware who use a str11f without external ram, am I limited in the size of the application that I can program with the IAP, as I only have 64k of internal ram ? (my application is actually of 140kb in debug)

2) I think I must change the scatter file of my application if I want to program it with the IAP, as the load region won't be the same. Correct ?

Anyway thank for the help so far
