I've added a single line to my code c code, and now it doesn't boot from flash at all. The original code was fine. The line I've added is asm (" RSBX 1, 13"); I want to change the general output signal XF to LOW. Is there any problem with this. Thanks,

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

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

Hello all, New member here. I have a C5402 EVM board with cables etc but absolutely no software. Obviously, I have the important part, but it is pretty useless without any DSK. I can buy the CCS from ebay but I'm not sure that this will contain the drivers / flash progra

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

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

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).

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
