Hello, What is meant by memory mapped registers ? Are all the registers on c54x memory mapped? Can I boot the C54x in parallel boot mode using only an 8 bit memory mapped as data space? (spra618A says if there is no I/O space you will have to store the address of t

HI there. I'm not sure about the origin of the errors, but I do notice one thing: The documentation you refer to is for the 5x series, of which the 5402 is not a member. 5402 is part of the 54x family. Maybe this has something to do with why the example will not work properly.

I am using a Spectrum Digital evaluation board with the 5402. I have my emulator connected. I am trying to get interrupts working when I boot with the bootloader from external flash memory. I can see my program run, however, I am not able to get interrupts operating properly.

I'm looking for any pre-existing tools that can do what I want before I write my own :) I need to take the final COFF file and convert it into a 'c' header array that I can use to boot the dsp from a host processor connected to the HPI. Simple RLE compression would also be ver

Hello everyone. I've decided to build my own HPI bootloader for the C5410 and i found some problems concerning the addressing. In order to boot the code I have to write the program in the DSP memory during the reset. I used the DSK coff extractor of the DSK5402 to

Andrew- What Microsoft did with X-box is interesting. They faced a similar problem -- no EEPROM on the processor itself. So they used a Flash ROM device with a small bootloader (processor) to handle decryption during boot. They did some things with JTAG also, like

I'm coming back, Hi guys, I have another question, now is about the dsk5402 reset and subsequent boot loading. My DSK has the MP/MC# pin grounded, and i'm loading the .out file using the parallel port. Reading the spra618 i find that the

Dear all I have started on the design of a stand alone board with a C5402. I have been using the DSK up to now. Three aspects that I dont have clarity on: 1. The program for the DSP should be loaded from flash memomy. How does the onboard boot loader work? 2. How will I

Re topic 4: Tom, I've got this going ok to give two hex files to boot a 5410 from 16 bit flash( 2x 8 bit devices) in data space. Do you mean you're not getting a file starting with 0x10AA (16 bit parallel load code or whichever one you're using)etc ? I had a situation wh

Dear All, We are developing a project based on TMS320c541 .We wanted to know the memory location at which the bootloader code in c541 is written ,and whether it is factory programmed or we will have to get it programmed through TI depending on our Boot Mode. I wi

We are using a C5420 in our design. I cannot figure out how to boot the processor, since it does not have a bootloader in internal ROM. I am trying to figure a way to map the reset vector at 0xFF80 to external memory (an EEPROM) at reset, but the documentation is ambiguou

I'm running a 5402 in microcomputer mode (using the bootloader to boot from flash). The DSP starts up OK then the \DS gets stuck in the active state. I've checked EMU, HOLD and MSC/READY pins thinking they could be the cause but they all look good. Any thoughts? Brian

Hi I have a small program written in C-code. This program should toggle the XF pin. I made this small test program to see if I was able to bootload something. I use the McBsp0 16 bit serial boot mode, but so far I have not been able to make this program run a

Hi I would like to bootload the TMS320C5402 from Flash-ROM using the Parallel Boot Mode. How can I put the correct word at the memory location 0FFFFh (IO-Space)? What is the correct Bootloader Recognition Byte (BRB) for this case? Does anyone have more Information

I remembered when I was using CCS1.2, I had problem related to RTDX when the code is boot from ROM, instead of downloading from CCS. So when I remove all RTDX related components, everything works fine thereafter. In your case, you might want to check the following

Hi everyone, I am experiencing problems with 5407 when the power supply is cut for some miliseconds. When returning, the program is properly boot loaded from the external memory, but executed on a wrong way. With a longer cut of supply this does not happen.
