Hi all,
I am very new to DSP programming. I am trying to initialize a Look-up table (float array) in Flash memory as I can't store the data in RAM memory due to its huge size. I have always used the default 28335_RAM_lnk.cmd linker file (which purely uses only SARAM). I know I need to make some changes in the linker command file to use the Flash memory. Also, should I use const float instead of float while initializing?
And to make my doubt more specific, I am not going to write anything on flash during execution (Only store them as .econst - initialize as global const float array). I just want to read few data from the look-up table (stored as an array) and use it for computation in ram debug while execution.
currently, the linker command file sector initialization lists as follows
codestart : > BEGIN, PAGE = 0
ramfuncs : > RAML0, PAGE = 0
.text : > RAML1, PAGE = 0
.cinit : > RAML0, PAGE = 0
.pinit : > RAML0, PAGE = 0
.switch : > RAML0, PAGE = 0
.stack : > RAMM1, PAGE = 1
.ebss : > RAML4, PAGE = 1
.econst : > RAML5, PAGE = 1
.esysmem : > RAMM1, PAGE = 1
IQmath : > RAML1, PAGE = 0
IQmathTables : > IQTABLES, PAGE = 0, TYPE = NOLOAD
what should I do to store it in FLASH. Please, someone, help me out.
Regards
Shiva
