TMS320C6713 board loader

Started by Unknown ●February 8, 2005

Hi all,

I\'m new on this list and I will really appreciate any help with this problem as it is halting all my work.

I have recently purchased a TMS320C6713 board and I have found out that there is no command (DOS) for loading a program onto this board and the IDE of the Code Composer Studio becomes necessary. As I have to run many experiments
(hundreds of thousands) this option becomes infeasible. I have tried using
gel files (as start up) but for some reason the instructions do not
execute sequencially. Another option is using the libraries for perl but
unfortunately they do not come with the version of the CCS that is
included in the kit.

Has anyone come across the same problem?

I look forward to hearing from you.

Cheers,

Yes, I have come across this problem too. I had planned on using a VC++
program, to load the 6713 DSK but have found out, like you, that CCS needs
to used unfortunately to load it. I guess the 6711 DSK had direct APIs
that could be called to load and run the board, but that functionality for
some reason has been left out of the 6713 DSK. It might be something about
the USB connection.
But Id be interested if anyone has any ideas on this as well.
One possibility, I guess, is to try and use RS-232 from the PC side to a
McBSP on the 6713. Someone had suggested hyper access for this, which
costs about $100. On the DSK side, the flash would have to be programmed
with some kind of initial bootup, where it configures the McBSP and
implements the software UART. And once that is running, the code could be
loaded. But thats a lot more effort than anticipated!, if it works.
Regards,
Robert

As you mentioned, 6711 used to have *ld* program in bin utils. I
havent checked for the same in c6713 but assuming that you have
checked and it is not there.If thats the case, then I guess(just
that!) TI is maneouvouring itself into a position where CCS is
indespensible for TI DSP debugging and algorithm development. Though I
have to admit that am surprised that TI would not provide a loader
program any more.

Anyways, many of the early attempts at having a non-CCS development
methodologies seem to have fallen by the way. Among the few remaining
non-CCS options what i would recommend is a software program called
DirectDSP made by one of our list's active member's
company-Signalogic. Not sure though if DirectDSP supports c6713 but
may be signalogic could help you on that.

As the "keeper" of DirectDSP software, I can say this:

1) It does not support C6713 DSK board because the combined USB-JTAG interface is
slow, around 20-30 kbyte/sec. Neither USB or JTAG by itself should be that slow, but
it's something in the Spectrum Digital implementation. I'm sure they could have made
it faster, but as you say, that is not TI's purpose in making inexpensive DSK boards
that provide both showcase and reference design for their chips.

2) If someone on the group can make an HPI daughtercard for the DSK board and show
basic HPI register-level connectivity from a simple C program, then we can port the
parallel port driver in DirectDSP to it. Such a daughtercard would look something
like this: __ HPI-PP daughtercard
__________/
___| \______/ |______
| | | |
| ========== <--------- HPI connector
| |
| || || |
| || ||<-------- standard daughtercard connectors
| || || |
| || || | <-- "new style" DSK board The HPI-PP daughtercard must:

-be small and super cheap

-have standard DB25 male connector, as on DSK 6711

-not overlap the main daughtercard area of the DSK board;
i.e. the board-to-board connector should be as close to
the edge of the PCB as possible

-have mounting standoffs at corners with height that
reaches to the surface the DSK board is resting on
(to provide strain relief on the board-to-board
connector). Mounting holes -- or some mechanical
method -- to the DSK board itself would be better,
but SD has not allowed for that

-provide 8-bit access to HPI registers in EPP and
EPP+ECP PP modes. That means the daughtercard needs
a small CPLD with state-machine that:

-on writes, aggregates even + odd bytes then issues
16-bit write to HPI

-on reads, makes 16-bit HPI read, sends even byte to
parallel port, stores odd byte for next PP read

the state machine should reset HHWIL signal to zero
as often as possible; e.g. on Reset, on two consecutive
even or odd accesses, etc.

-provide Reset control over the C6713, in addition to
HPI register access

-provides 5V to 3.3V translation, provides series R
protection for PP lines, etc. We can review the
schematic...

We keep thinking this is a great student-level project, but we keep finding
production level design things to put our entry-level engineers to work on, so the
HPI-PP daughtercard project never gets traction. To put that another way, it's a fun
project, but not very attractive commercially.

DirectDSP has both WinXP and Linux drivers, PP and PCI. Basically any time the HPI
is accessible.
