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...

1. The primary bootloader (in ROM of C672x) copies only 1024 bytes from any chosen external source, i.e. I2C, SPI, Asynchronous.. Memories. 2. The secondary bootloader which should be within this 1024 bytes should copy the rest of the code(application) to RAM and start execution. 3. Supposing my application is small enough and can fit inside a 1MB I2C EEPROM, where can i find a second...

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 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.

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. The bootloader stub then configures the EMIF and then copies all sections from Flash to ROM on bootup. 1) How is the EMIF configured to copy the first 1KB of bootloader stub from F...
