Hopefully I understand your question. How to get the address of the boot table into external memory at FFFFh so the bootloader knows where to find it. I use Flash memory and use the FlashBurn utility from TI to burn the Flash initially. In Flashburn there is a little checkbox l

Hi guys, I would like to thank all the great helps. I solved the Flash content display problem now. It's because I didn't confirm that the .hex file was actually written in the FLASH and it WAS NOT. I rewrote the .hex file and now everything is ok. Especially thanks to T

Ok I will be a little more specific with my question, it was late on friday when I aksed the other one and I guess I babbled. The flash.h file states that a write to address 0, sector 0 is the address 0xC000 as viewed by the cpu. Is this true? If I write to address 0 sector 1,

Hello everyone! Can anyone recommend a FLASH EEPROM for serially booting 5402? I am specifically looking for smallest possible size, power consumption in standby mode and price. The size should be about >=32kbits. I am also looking for code examples for serially boot

hi all, I wrote drivers for the onboard flash on tms5402 dsk. For block0 and block 1, Iam able to program and erase flash memory. but when i run my program to check for the protection of other blocks (2,3,....) my dsk is going out of control. I dont see any changes on the conso

I'm modifying the CCS FlashBurn utility to work on my custom target hardware. So far I've been able to erase the flash and write to it (after changing the volitile 'c' pointers to call custom assembly routines to address the flash). The problem I have now is that the checksum

I'm trying to program flash addresses above 0xffff using the WRITA and READA instructions. It is not working. Is the timing of the address bus the same for these instructions as for normal data space writes? Flash programming is fine below 0xffff. The only thing I can think of is tha

I think that happens when you try to make CCS load things into external memory while you have the Flash memory enabled instead of the SRAM. For external memory, CCS can only write to SRAM not Flash. But I don't even know if you are using a DSK or what so this may not apply. If

Hello, Is it possible to use the OVLY bit in the PMST register to do swapping of memory pages between the internal memory of a C5410 and a flash chip?? The board that I am working with has a flash chip mapped to the same areas as the C5410 memory and I don't have a clue yet on

I use TI's C5402 DSK and i have the following problem. If my program exceed address 0x4000 then i get a data verification error. I changed the jumper that enables or disables the FLASH , so that flash is enabled by i still get the same error. Sometimes the program can be downloaded but it

from lots of pdfs about 5402 of the web of ti,i found that the bootloader address is from 8000h to ffffh, which make the total memoty size is 32k,but my flash is 256K*16,my question is whether my flash wasted? if my program is larger than 32k,how can i do? my english is

Hi I have a little problem in bootloading the 5402 in the parallel mode. I'm using a 8-bit wide flash memory for bootloading the DSP (5402), but I cannot get any result; could anyone help me with an example of a properly programmed flash memory cintents for bootloading i

Hi, I am using a C5402 in my own prototype PCB which includes a 256KWord FLASH & 2 64KWord RAMS. The Flash and Data RAM can be swapped using an attached CPLD. I have developed the DSP/BIOS source code to the point where I can use hex500 to create a boot table

Hello all, I am using TMS320DM270 (ARM7 & c54x DSP) chip. I am trying to interface harddrive(20 GB) to the external memory interface region 1 (Compact flash region) of DM270. DM270 datasheet tells Compact Flash interface doesnt support trueIDE mode.

We are using a 4 Mb Flash memory in our design. It has been given in the DSP data sheet that only A0-A15 can be connected as data space whereas A16- A19 can be used only as the program space. The code size in our case is nearly 4Mb. But 16 address lines can address 64kb

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,
