Hello,
I'm developing a project using a TMS28335 microcontroller, but I'm new in these topics so I've just copied some code from several examples.
I'm running a program from FLASH memory, and I was defining an array of size 2048 without having problems, but now I need to change its size to 4200 but I got this error:
program will not fit into available memory. run placement with alignment/blocking fails for section ".ebss" size 0x1048 page 1. Available memory ranges: F28335_FLASH_FlashingLeds.CMD /Prueba3 line 146 C/C++ Problem
My code is:
Uint16 Aux1;
Uint16 Datos[TAM]; // where TAM is 2048 and I need it to be 4200
Uint32 Suma;
Uint32 Promedio;
Uint16 DatoRec;
I suppose that section .ebss has not enough space to include all the variables, so my question is, how could I change the section where variables are assigned?
This could be a simple question, but I'm really confused with all this programming, that's why I have copied some example code sections.
Thanks for your help.
Hello, Christian.
If you use "Datos" as read-write array, it must be placed only in the memory (.ebss, by the compiler). Otherwise, please use "const" modifier to put "Datos" to the FLASH.
For the available memory mappings, please refer to the sprs439m.pdf, page 35. You have 32k (in words, 16 bit) memory for use by program and data.
Please, show your linker script (F28335_FLASH_FlashingLeds.CMD). To fit your data, you need to extend ".ebss" section in a way:
.ebss : > RAML4 | RAML5 PAGE = 1
instead of default one:
.ebss : > RAML4 PAGE = 1
Array of size 2048 is 0x800 words and will take just a half of the RAML4. When you grow your array to 4200 you'll take 0x1068 words of the maximum 0x1000 words available per memory block.
Hope this helps.
Hello Christian!
Try to make the following changes to the file F28335_FLASH_FlashingLeds.CMD:
.ebss : > RAML45 PAGE = 1
data : > RAML45 PAGE = 1
...................................................
SECTIONS
{
Net_terminals: > RAML45,PAGE = 1
Controller: > RAML45,PAGE = 1
IBx_addr: > RAML45,PAGE = 1
Buck1Loop: > RAML45,PAGE = 1
Buck2Loop: > RAML45,PAGE = 1
DataLogTST: > RAML45,PAGE = 1
GraphData: > RAML45,PAGE = 1
}

Igor
Hello Anton and Igor,
Thanks for your answers, I've changed my CMD file at the .ebss part.
Trying with:
.ebss : > RAML45 PAGE = 1
makes I still got the following error:
no valid memory range(NULL) available for placement of ".ebss" F28335_FLASH_FlashingLeds.CMD /Prueba3 line 146 C/C++ Problem
I'm using CCSv5, by the way. Changing the code to:
.ebss : > RAML4 | RAML5 PAGE = 1
now gives me this error:
program will not fit into available memory. run placement with alignment/blocking fails for section ".ebss" size 0x10b0 page 1. Available memory ranges: RAML4 size: 0x1000 unused: 0x1000 max hole: 0x1000 RAML5 size: 0x1000 unused: 0x1000 max hole: 0x1000 F28335_FLASH_FlashingLeds.CMD /Prueba3 line 146 C/C++ Problem
I also have 2 questions:
1. If I change the line that starts with .ebss, I must change the line that starts with data, and all the lines at SECTIONS, as Igor suggested?
2. Additional to the data I have, I need to declare more variables. Which memory section could I join to RAML4 and RAML5, when solved the actual problem?

Thanks for your help!
Try to change memory sections definition.
Replace those segments:
RAML4 : origin = 0x00C000, length = 0x001000
RAML5 : origin = 0x00D000, length = 0x001000
with this one:
RAML45 : origin = 0x00C000, length = 0x002000
And then correct ".ebss" and others' placement:
SECTIONS
{
// …
.ebss : > RAML45, PAGE = 1
data : > RAML45 PAGE = 1
DMARAML4 : > RAML45, PAGE = 1
DMARAML5 : > RAML45, PAGE = 1
// …

Buck2Loop: > RAML45,PAGE = 1
DataLogTST: > RAML45,PAGE = 1

}
> 2. Additional to the data I have, I need to declare more variables. Which memory section could I join to RAML4 and RAML5, when solved the actual problem?
You may use RAML6 and RAML7 when you'll need more memory or want to separate data between segments.
program will not fit into available memory. run placement with alignment/blocking fails for section ".ebss" size 0x10b0 page 1. Available memory ranges: RAML4 size: 0x1000 unused: 0x1000 max hole: 0x1000 RAML5 size: 0x1000 unused: 0x1000 max hole: 0x1000 F28335_FLASH_FlashingLeds.CMD /Prueba3 line 146 C/C++ Problem
This error happens, cause' you can't split continious data into two memory segments even they have no gaps.
Hello Christian!
You should replace all the lines that were mentioned. Changing only one line does not make sense. If you want you can send your project. Also you can try following variants:

Notes:
Memory blocks on F28335 are uniform (ie same
physical memory) in both PAGE 0 and PAGE 1.
That is the same memory region should not be
defined for both PAGE 0 and PAGE 1.
Doing so will result in corruption of program
and/or data.
L0/L1/L2 and L3 memory blocks are mirrored - that is
they can be accessed in high memory or low memory.
For simplicity only one instance is used in this
linker file.
Contiguous SARAM memory blocks can be combined
if required to create a larger memory block.

/* Define the memory block start/length for the F28335
PAGE 0 will be used to organize program sections
PAGE 1 will be used to organize data sections
Notes:
Memory blocks on F28335 are uniform (ie same
physical memory) in both PAGE 0 and PAGE 1.
That is the same memory region should not be
defined for both PAGE 0 and PAGE 1.
Doing so will result in corruption of program
and/or data.
L0/L1/L2 and L3 memory blocks are mirrored - that is
they can be accessed in high memory or low memory.
For simplicity only one instance is used in this
linker file.
Contiguous SARAM memory blocks can be combined
if required to create a larger memory block.

BTW, you may try to correct a little bit a previous statement before changing a number of lines:
.ebss : >> RAML4 | RAML5 PAGE = 1
The ">>" operator used to indicate that an output section can be split into specified memory ranges, spru513e.pdf, p.195, 7.5.4.7.
Thanks to both of you! I finally changed the memory section lengths, and it worked fine.
I will also review the variants you sent me, and the use of ">>" operator.
