Hi. Is anyone familiar with booting an application from FLASH? I have followed very carefully what the folks at TI have suggested. Obviously and expectedly, it did not work. I have also tried everything under the sun I thought was reasonable but to no avail. I am now convinced that the so called DSP specialists at TI really know nothing. If anyone know, I will appreciate any hints and better yet solid detailed discussions. If anyone is interested in the same subject but is encountering the same problem, we can work together adn hopefully we can hack this out among ourselves. Also if anyone is familiar with desiging a custom DSP board, any sort of hints are appreciated. As with the above, I would be very interested in discussing anything relating to this topic. I would also like to work together with anyone trying to do the same thing. Please email me at or reply with your email. Thanks! |

RE: [c6x] Booting from FLASH
I haven't tried to bootload 6x, but I did it with 54x quite successfully, with no problems of any kind. I had to read quite a lot of documentation that TI made available on the subject to figure out how to do it, but after it "just worked". The questions I had to answer were:
The (1) was easy - just follow instruction in a data books/app. notes. The (2) was little bit more involved and required reading software manuals on linker, compiler and COFF converter. Once I read and understood it all, I had no problems. Now, could you be a little bit more specific on what problem you having and what you tried to do? Like what processor, what kind of flash, what you tried... In my experience, TI people usually quite helpful and they do have some knowledgeable engineers that can help you if you ask right person a right question. Mike. -----Original Message-----

We have a c6211 design that boots from FLASH. The only hardware related things were to set the boot mode with pull up/down resistors on the HPI pins and locate the FLASH on the CE1 address space. The other trick is to make sure that the bytes are in the FLASH in the right order. The DSP packs them to make 32bit words, our FLASH is 16bit wide and the programmers default was to write the two bytes sequentially into the 16bit word so that when the DSP read them the byte pairs were swapped and the instructions were garbage.

A Feynman- Do you have the DSK C6211 schematic? The DSK C62xx boards boot from Flash. Just follow the schematic for a starting point, and then go from there. Asking TI pretty much does not work unless you are persistent for weeks. Your best bet is with peers, news groups, 3rd party vendors, published reference designs (DSK), etc. TI support knows this, so they tend to wait a bit and see how who else helps you first ;-).

hi, we had also designed our DSP 54x based system on the same way, means that DSP software will be in flash and in reset that code will be downloaded to DSP through the mastering of one master processor(which will control many DSPs). After that DSP will be taking out of reset. This will ensure that after reset DSP will jump to vector table of ISR and it will start executing. >From your mail what I can guess that you are not able to start DSP after downloading to the DSP. For this check the status registers for proper initialization. If this doesn't solve, please send the details of your problem, I will try to debug it.
