Hi,

I wont to ask a litte question.

Where can I find some documentation on Hex6x?

In this example : ti\mcsdk_2_01_01_04\tools\boot_loader\examples\ethernet\simple

Hex6x simple.rmd

where simple.rmd is in the follow

simple.out
-a
-boot
-e _c_int00
-order L

ROMS
{
   ROM1: org = 0x0400 " ?? org what rapresents??", length = 0x0080, memwidth = 32, romwidth = 32
          files = { simple.btbl }

}

how can I build an image more big? I have to delare evry time the length?

thanks

massimiliano,

Please refer to chapter 11 of this guide: http://www.ti.com/lit/ug/spru186w/spru186w.pdf

"org" represents origin. The default value is 0 if not specified.

For a bigger image, you will want to increase the "length". If it is not declared, it is defaulted to the entire address space. If your image is smaller than the length specified, you can use the "fill" option to fill in the holes with a specified value.

Let me know if this helps.

Thank you Ivan,

It's very helpfull!

I Have a little program that loaded by RBL ETH runs, but if I will try to create an "image" for example

"C:\ti\mcsdk_2_01_01_04\examples\ndk\client\evmc6657l\Debug\client_evmc6657l.out" the DSP seems jump to entry point but don't work.

I think that not all the options are correct or the way to build a eth boot is incorrect.

My Hex6x options are:

client_evmc6657l.out /* File in input */
-a
-boot
-e _c_int00  /* Entry Point */

-order L

-memwidth 32
-romwidth 32
-o buildimage.btbl

My goal is to build an IMAGE of a custom IBL for etherneth boot.

Have you an Idea? Where I'm in wrong?

thank you

massimiliano,

Did you also use the bconvert64x.exe and bootpacket.exe tools for formatting? How are you sending your "image"? (Are you using pcsendpkt?)

I'll have to point you to our bootloader user guide, http://www.ti.com/lit/ug/sprugy5b/sprugy5b.pdf, which describes the format that the DSP expects. I personally have not tried loading a "large" program via RBL Ethernet boot - I will double check if there are any limitations to be aware of. As an alternative, TFTP boot is proven to work with the same images as the other i2c boot modes and might be easier to work with than RBL Ethernet boot.
