Dear Group I have a STMicro M29W010B 8-bit wide Flash memory module connected to a C5402 on a custom board. The bootloader must load the program in flash to onboard memory and start executing the program. The start of the stored program is at address 0x4000. According t

In TMS320VC5416 DSP, I got a weird problem. I used DMA to move code from extern flash memory(SST/ST flash) onto DSP. If I moved code onto DSP in random block size, the result always doesn't work fine. Strangely, if DMA move code in one word in each time. The result gets better

George, I did read the SPRA618 a few times, but I missed the point concerning the reading of the address in 8 bits. But (and you mention it) the information was there... Thank you for your very clear, complete, and helpful answer. Raymond >

Does anyone have any experience using the flash.h functions on the 5402 DSK as far as I figure it I have everything from 0x10000 up to use even after I have stored my program in the bootloader (assuming i only use on chip ram). I've tried things like flash_write, and flash_read, but

Ok, I believe I have programming the flash down. I am happy with that. I can load a simple program, have the reset vector hit it, and it is off and running. One more thing I am confused about. I am using a boot.asm file from TI, v3.10. It does have some code for the

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.

What could cause a prog(A) call that has worked in previous instances to fail to work properly? This is code I have used in several reflash routines, but in my latest implementation it is writing to memory location 0x00 (although it still seems to successfully erase the flash).

I have the program in flash. When I do cold reboot, it does not come up properly everytime, sometime, it goes into some dead stage. I either have to press the reset button or cold restart again? How can I solve this issue? thanks Andrew

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

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

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
