Hi, ? We are using the attached bootloader, boot_TI.asm, provided by TI for our application. This bootloader was provided with fpga_loader.pjt for Flashburn utility. We found that the when we modify the file as in boot_TI_hang.asm, i.e, change the emif_values: to above the _boot function, we are facing a strange issue. When we flash this bootloader, booting from Flash happens correctly mo...

Hi All :), I'm using a TMS320C6455 DSP processor, i've few quires 1) I read in the boot loader user's guide (spruec6b.pdf) in the section 2, bootloader features its given that the bootloader is permanently stored in the ROM of the DSP at 0x100000. Does this mean that an on-chip bootloader will be already present in the DSP. and We need not have to program this. 2) What is the I2C Dev...

Hi, I have a clue about what may be wrong. I suppose the problem is that the SDRAM is not stable at the time when the second level bootloader transfers the data from the FLASH to the SDRAM. All the necessary settings are properly done, but there are some minor errors sometimes. After a detailed analysis over the working NON/BIOS bootloader I have identified the line after which the RAM becomes...

Hi, I am using EVMDM642 board in Flash boot mode. I have a few doubts regarding bootloading using Flash. The bootloader stub (1 KB) is copied from Flash base address 0x90000000 to the RAM address 0x0000.

But when the DSP jump to the ent...
