TMS320F28379D: Wrong initialize of big array of structs (.ebss)

Juan Galbis

Part Number: TMS320F28379D

Hi everyone

Currently im working in a modbus table map. Formed by a big array of structs.

I initialize this array of structs in a .c file and extenalize it in a .h file extern modbus_map_t hr_map[NUMERO_HOLDING_REGISTERS_SLAVE];

The struct is the following

This big array belongs to .ebss, and im currently storing this at GSRAM, joining 4 sectors .ebss : > RAMGS0_4, PAGE = 1,

The problem comes before run the code, its possible see the values of the structs with the debugger and many of them are correctly initialized but some of them are wrong, are not pointing to the correct variables, and values.

Anyone know how to solve this?

Many thanks in advance

You are using EABI or COFF format ? Also I am assuming this is on CPU1

Dear Vivek

Where can I find, EABI or COFF format?

Yes in cpu1.

As you can see adress 2091, 2092, 2093 are not correctly initialized, is very extrange

Many thanks. In addition this only happends when im debugging. Out of debugging, 'in production' the addresses are correct because I can communicate with them.
