It's not as efficient to use, but it should work (I just wrote a test program and it ran fine). For example, lets say you have 2k of ram available in 8 banks and create 9 129 byte arrays for a total of 1161 bytes. Arrays of pointers to rom will be placed in an idata section unless properly qualified. Infinite Fibonacci sums - diverge or converge What's the fastest way to generate a 1 GB file containing only random numbers? Source
The paragraphs you pointed out were what I had found and led me as far as they did. (And I'm not saying I didn't miss some major point along the way) Anyway I will have a look at your map file. (two eyes may see more than one ) edit: viewing your map file it seems you simply running out of memory You have to expand the size of a section in the linker script. The fix for this error is here. check it out
Perhaps, others will help. When you compile your code it will now use this linker script instead of the default one, but only for this project. For each initialized data section, the linker creates a section in program memory. The error message points you to the map file wich is a good place to look for when you try to understand what's going on.

Fixing the Error The fix is simply to instruct C18 to use more than one idata/udata section in a source file. Alex gopherbot commented Apr 19, 2013 Comment 12 by mikaelbrg: Alex, https://golang.org/cl/8676050/ allows my project to be built (sotest, bitbucket link in original report), but it fails at runtime. Not sure.
At link time, the linker attempts to place each section into a memory region. Ipc Sections Log in / Username Password Verification Stay logged in Login Forgot Your Password?

To stop this add the word PROTECTED after the DATABANK definition. Mikael alexbrainman commented Apr 22, 2013 Comment 17: @mikaelbrg, glad you have a workable solution. The section names can be any valid C identifier; the ones shown above do not have any special meaning. We will leave this alone and combine the previous 3 RAM banks to make one larger RAM bank.
In the example above, the section name is switched to udata1, and a is placed in the udata1 section. https://www.chiefdelphi.com/forums/archive/index.php/t-45403.html You can create named data sections by combining banks in the linker and put #pragmas around the variables to locate those variables in that section. #pragma Udata And you shouldn't have that problem anymore.. Build with "go build sotest" What is the expected output?
I'm not sure if you are using C18 or not to compile your code, but even if you aren't you will likely need to modify your linker script to increase the Section '.udata_Main.o' length=0x00000648 Errors : 1 Thanks BasicPokePosted by Dennis Clark ●May 16, 2008> I am getting the following error in MPLAB 8.10. Notice that bank gpr15 is only 0x5F (96 bytes) in size, this would have given us a total of 607 bytes - perfect. than me and your coworker wasn't so much wrong because the problems seem to be in prog.
We are going to use the 18F26K20 for this example. Owner changed to @ianlancetaylor. I've isolated it to a single line I comment or uncomment to get it to build properly or give a can not fit section error. have a peek here The linker will divide and reorganize your data locations to fit it into the various data blocks available.
The End devices fail to connect to the network after 16 nodes are already connected to the network. If it were a data memory limit you'd see udata or idata as part of the error message. this doesn't make sense to me (the "code" directive is for program mem. (ROM) and the xdata is for data mem. (RAM)) just an idea - is the idata section declaration
Increasing the connection size from 8 to 16 gives the following error. Should I be concerned about "security"? Data memory 963 out of 2k After I split user_routines.c into two files... -8722 builds with 15871 of 65K program memory, 1145 out of 3935 data memory. - 8520 fails to Take a look at the .map file with the data declared as "rom const" and again with the data declared without the "rom const" and see what section and what address
Where do I find the linker section you are referring to? –cookie monster Jun 17 '13 at 20:17 Yea I am still stuck, not sure how to follow the Determine the total size of the large sections, in bytes. A variable or array must fit into a databank. http://futurecityforum.com/error/error-section-entry-scn.php I break that one up and then it fits them all, but previously, would choke again in the same manner on a different file.
It appears my statically initialized user variables won't fit in one FF "bank" or "section"??? .
