Dear Jean, this may seems like a joke but it isn't. I suggest you to first read the silicon errata of the device you will use. We have to change our design several times due to the hardware silicon bugs in the 5509. Good luck ! marko jeanpierrepoulin wrote: > Hi, > I'm starting out in the brave new world of TI DSPs (from the simpler > days of PIC designs), and am facing a very steep learning curve in > front of me as I contemplate the design of my next DSP circuit. > > I can handle the software part because of my background, but the > hardware appears daunting! > > My next circuit needs to: > - Support SDRAM & Flash > - Support JTAG interface > - Read image frames from a CMOS camera > - Read/Write to a CompactFlash card / Hard Drive > - Communicate with an Ethernet MAC/PHY chips such as the Crystal > C8900A.

In regards to the CPLD I would reconsider//I'm a convert. They are very cheap and easy to work with. I've used Coolrunner II 32 cell parts Cost (approx $1.50 US) and am now using Lattice 4000z 128 cell parts (less than $3.00 US). Both are very low power, easy to work with, and have free tools. I just use the schematic entry for the most part Don't have time to become a verilog person). As far as production programming both can be programmed with a batch style program and it takes only seconds. I keep them on a separate JTAG chain than the DSP to keep it simple.

I would strongly recommend you try some simple Verilog and slowly migrate your projects, especially when you start using larger devices. Verilog is very easy, and saves a lot of time in certain areas -- like a 3 x 32 bus switch -- ya put that into a schematic. And when you have to move your design from one device to another (or one vendor to another) it can make life a lot easier. I have found the logic vendors are inconsistent with schematic tools and upgrades -- not a reason to not use them, especially at the top level in a multi-person, multi-block design -- but definitely a reason to avoid schematic when Verilog makes more sense. And your suggestion to separate DSP and logic JTAG chains is right on. We do that without exception. Although TI and Xilinx say their devices will function Ok on a chain that includes each other, we never could get it work. Everyone knows how cantankerous CCS can be sometimes; no need to live dangerously and invite more trouble. -Jeff > --- In , Jeff Brower <jbrower@s...> wrote: > > Marko- > > > > > this may seems like a joke but it isn't.

Wa are using the F revision. All of the versions are buggy, but they fixed some things in the latest versions (F). See the sillicon errata. We are still digging into a problem we discovered with USB. Randomly we are missing transactions. We still don't know if this is a HW or SW bug. The behaviour is that from a certain point we don't get any more USB interrupts, until we unplug and then re-plug the device. In think the major bug you should be aware is that CLKOUT is out of control when booting from FLASH (not via CCS and JTAG). Also there are several bugs with sleep modes. marko Jeff Brower wrote: > Marko- >>this may seems like a joke but it isn't. I suggest you to first read the >>silicon errata of the device you will use.

Yeah I've noticed the Rev D errata has 109 CPU advisories alone, not counting EMIF, DMA, etc. I will look into the CLKOUT issue -- I did not see it in the errata.

We are booting (note, this is not the same as executing) the device from EMIF. We have an 16bit wide flash device attached to it. Regarding the CLKOUT issue see advisory DL_13: "...SYSR does not control CLKOUT divisor when a JTAG connection to the debugger is not present..."

Seems to me the silicon F is not a big improvement, but if you checkout the silicon errata for the 5509A you will see the bug list drop dramatically. As for the USB problem, I have a problem with the UART. After some period of time (seems random), the UART no longer generates interrupts when characters are received!! Sounds like the USB has the same underlying problem. Are you using GIO calls?? Paul --- In , Marko Panger AGB Lab <marko.panger@a...> wrote: > Wa are using the F revision.

After a discussion with TI we tried the 5509A, but with no success. The code didn't worked. This was about 5 moths ago.
