I work with the HVPM_Sensorless_2833x exapmle project, I added some functions to new .c file named "Functions.c" and there is building error about the ram size:
---
"../F28335_RAM_HVPM_Sensorless.CMD", line 124: error: program will not fit into
available memory. placement with alignment/blocking fails for section
>> Compilation failure
".text" size 0x1c26 page 0. Available memory ranges:
RAML1 size: 0x1800 unused: 0x1800 max hole: 0x1800
error: errors encountered during linking; "HVPM_Sensorless_2833x.out" not
built
gmake: *** [HVPM_Sensorless_2833x.out] Error 1
gmake: Target `all' not remade because of errors.
**** Build Finished ****
--
It shows that the problem is in the "F28335_RAM_HVPM_Sensorless.CMD" file and the line is " .text : > RAML1, PAGE = 0"
My code is not too large and I have not got big arrays, I think problem is about the page size, code must use other RAM pages, builder must use other pages but it does not? (when I delete some functions, it builds) (I use RAM boot, the project does not have FLASH boot)
I attached the .cmd file.

/* 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.
