SPI0 Flash boot problem.

Other Parts Discussed in Thread: OMAP-L137

Hi,

I can't boot my program from SPI0 Flash onboard EVM memory. Program uses only OMAP-L137 DSP side, DSPBIOS Timer1 , one CLK function, one Task, RS232 460kbs (P1 on EVM). With CCS3.3 in debug or release mode program works correctly. I added code listed below to repleace GEL command:

void main(){
Setup_System_Config( ); // Setup Pin Mux and other system module registers

Setup_PLL(); // Setup PLL0 (300MHZ ARM, 300MHz DSP, 133MHz EMIFs

Setup_Psc_All_On( ); // Setup All Power Domains

Enable_ARM();

....}

After that with CCS3.3 program has been working correctly.

Functions are copies of GEL file part, I changed only PINMUX to feet my dotherboard and removed GEL commands.Then I made AIS file ( 1316 KB size ) and sent it to SPI0 Flash using spiflash_writer_CCSv3 dspais option. It took about 15 minut and veryfication was ok. Then I powered off EVM and changed BOOT switch (7 off, 2 on, 1 off, 0 on, 3 off). After power on program didn't start on standalone EVM. What is wrong?

I did this same with LED test program - succesfull. Mayby my program is too big?

Hi Adam,

Open CCS without connecting to the board, remove the GEL file and then connect. this way the GEL file initializations will not be done and you can try to find what is missing.

Also, make sure that the file that has the initializations do not have optimization enabled.

You do not need the Enable_ARM() function if you are not using the ARM.

Hi Mariana,

I did all you wrote me. Now I get message from File loader "Data verification failed at adress 0xc33a4b40 Please verify target memory and memory map". I think I have to add Setup_Memory_Map() function. But how does it write in C language: GEL_MapAddStr( 0xFFFD0000, 0, 0x00010000, "R|W|AS4", 0 ); Does CCS C compiler understand or not GEL_xxxxxx command?

Hi Mariana,

I did all like in Debugging Tips and still can`t find File loader error "Data verification failed at adress 0xc33a4b40 Please verify target memory and memory map". I get this message during program is loading (Loading sections .cinit: 0 of 1248156 at 0xc33a4b40). Please point me where can I verify target memory and memory map? Does it good place at the beginning main() for setup_system_config, setup_pll, setup_psc_all_on if I use DSPBIOS? Maybe it should start befor DSPBIOS inits main()?

Hi Mariana,

My program boots from SPI0. Now I have to guess why.

I'm glad to hear that, good news. What did you do differently?

Make sure you did not remove the GEL file, but just commented the initializations that you put in you program. This way CCS can access the memory.
