Steve, I used my own linker file (you can see a part of it in my previous post) to put data in a specific area of flash. I must keep this data with other code (a few C functions) since I move this entire block (.downloader) during field upgrading software. It works very well when I put only code in this block. When I try to add the data array in it, the linker send me an error of “section type conflict” which I don't understand.

Is that what you want to know, or are you looking to force the const data into a very specific area of flash? That is also possible by using an attribute, and modifying the default linker file to define another segment in the required area. For example, I have a 16K device, in which I put a data table. I want this to be in its own flash page, so it ca be altered at calibration time. I have this in the .x file for the linker: erasabletext (rx) : ORIGIN = 0xc000, LENGTH = 0x200 text (rx) : ORIGIN = 0xc200, LENGTH = 0x3fe0 In a C header file I have this: #define __erasablemem__ __attribute__ ((section(".erasabletext"))) And then in my code I have things like: __erasablemem__ const int a_variable; Regards, Steve Frederic Beaulieu wrote: > No one has an idea about this topics? > > > > ------------------------------- > > Frederic Beaulieu, M.Sc. > > Research and Development > > NewTrax Technologies Inc. > > http://www.newtraxtech.com/ > > -----Original Message----- > *From:* mspgcc-users-ad...@lists.sourceforge.net > [mailto:mspgcc-users-ad...@lists.sourceforge.net] *On Behalf Of > *Frederic Beaulieu > *Sent:* Wednesday, May 04, 2005 11:27 AM > *To:* mspgcc-users@lists.sourceforge.net > *Subject:* RE: [Mspgcc-users] Put code and const in a same memory section > > > > How I can specified for a memory section which type of data will be > put in there? > > > > -----Original Message----- > *From:* mspgcc-users-ad...@lists.sourceforge.net > [mailto:mspgcc-users-ad...@lists.sourceforge.net] *On Behalf Of > *Frederic Beaulieu > *Sent:* Wednesday, May 04, 2005 11:06 AM > *To:* MSP430 mspgcc Groups > *Subject:* [Mspgcc-users] Put code and const in a same memory section > > > > Hi all, > > I try to put a const array in a self-defined memory section (see > hereafter) used originally to put code but I obtained a “section type > conflict”. > > I can’t understand why. > > Any help will be appreciated > > Fred > > > > ----------------------------------------------------------------- > > Code: > > *#define* __downloader_area__ __attribute__ ((section(".downloader"))) > > *const* Byte1_t __downloader_area__ gb1PdaMessageLength[29]; > > > > Linker: > > MEMORY > > { > > … > > downloader (rx) : ORIGIN = 0x2500, LENGTH = 0x0b00 > > … > > } > > SECTIONS > > { > > … > > .downloader : > > { > > . = ALIGN(2); > > PROVIDE (__downloader_start = .) ; > > *(.downloader) > > PROVIDE (__downloader_end = .) ; > > } > downloader > > … > > } > > ----------------------------------------------------------------- > > > > > > > -- > No virus found in this outgoing message. > Checked by AVG Anti-Virus. > Version: 7.0.308 / Virus Database: 266.11.3 - Release Date: 5/3/2005 > > > -- > No virus found in this incoming message. > Checked by AVG Anti-Virus. > Version: 7.0.308 / Virus Database: 266.11.3 - Release Date: 5/3/2005 > > > -- > No virus found in this outgoing message. > Checked by AVG Anti-Virus. > Version: 7.0.308 / Virus Database: 266.11.3 - Release Date: 5/3/2005 > > > -- > No virus found in this incoming message. > Checked by AVG Anti-Virus. > Version: 7.0.308 / Virus Database: 266.11.3 - Release Date: 5/3/2005 > > > -- > No virus found in this outgoing message. > Checked by AVG Anti-Virus. > Version: 7.0.308 / Virus Database: 266.11.6 - Release Date: 5/6/2005 > ------------------------------------------------------- This SF.Net email is sponsored by: NEC IT Guy Games.
