Other Parts Discussed in Thread: CONTROLSUITE

Hi Team,

Do we have any TMS320C28346 example code for boot to external flash? which the cmd file should be look like as below:

MEMORY

{

PAGE 0 :

/* BEGIN is used for the "boot to FLASH" bootloader mode */

BEGIN : origin = 0x100000, length = 0x000002 /* Boot to Flash

will go here */

RAMM0 : origin = 0x000052, length = 0x0003AE

ZONE6A : origin = 0x110000, length = 0xF0000 /* 0x100000 XINTF

zone 6 - program space */

CSM_RSVD : origin = 0x33FF80, length = 0x000076 /* Reserved -

for compatibility to legacy C28x designs. */

CSM_PWL_PROG : origin = 0x33FFF8, length = 0x000008 /* 128-bit

password locations */

BOOTROM : origin = 0x3FF27C, length = 0x000D44

RESET : origin = 0x3FFFC0, length = 0x000002

....

}

Sorry for the delay answering on my side, have you looked at the below example directory in controlSUITE:

Best,

Hi Matthew,

Yes I see this example, but this should be boot to RAM as the cmd file is 28346_RAM_xintf_lnk.cmd.

Strong,

Your question is not clear. Are you asking for an example for Boot from external flash? (not boot to external flash).

Is the flash chip connected to the XINTF? SPI? I2C?

Exactly what is your question? Are you asking how to generate the COFF file that gets programmed in the external flash? Or are you asking how to load the code from the external flash by using the a boot-ROM loader option?

Have you looked at SPRUFN5?

Hi Hareesh,

sorry for confusion, it is TMS320C28346 without internal flash that connect to XINTF, and choose the bootmode "Jump to XINTF x16", The boot ROM will then jump to the address 0x10 0000.

question is do we have example project for this application? Thanks.

Strong,

We do not have an example for this specific case. Are there specifics that are not understood? If so we can try to work through them.
