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...

Hello All, I had query regarding bootloader for DM6437. I want to use on chip Rom Bootloader to fetch data from NAND flash. But the Bootmode pins[3 to 0] are set to 0000 not to 0111. Is there any way out to load prg from NAND Flash. Please let me know if any, Thanks, Amol

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 This is chandrasekhar from BEL, Chennai, India. i'm working with a board having TMS320C6727 DSP Processor, EEPROM(64K x 8),and RTC connected through I2C bus. On power-on, bootloading is happening (LED_BLINK_CODE of size less than 1024) from EEPROM without secondary bootloader. since my application code resides in EEPROM, i written secondary bootloader code to copy it to RAM....

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. 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...

Hello, Following the example in SPRA999A we've written a bootloader for our custom C6713B based card. Now we would like to add PLL configuration. Does anyone have an example bootloader which includes the PLL setup? More specifically how and where do you put in the requisite delays? Thanks, Bob

Hi, i am programming an application for TI DM6437 DSP and I like to use the watchdog for two purposes: 1. The bootloader loads the application, activates the watchdog and starts the application. If the application image is broken and does not start correctly (say after 10 seconds), then the watchdog resets the DSP and the bootloader can start a recovery application. 2. If the application ...

Hi, I want to create a secondary bootloader for C6713 DSP. I am using the SPRA999A document form TI for this purpose. The document suggests to create and link the copy table as follows .text : load = FLASH_REST, run = IRAM, table(BINIT) .const : load = FLASH_REST, run = IRAM, table(BINIT) I have used the same in my linker command file. BUt when I compile the project, t...

hi this is chandrasekhar.. my board is having TMS320C6727 DSP with EEPROM(8k), RTC etc., the primary bootloader is copying first 4K of bootcode from EEPROM into RAM and it is executing.. now i want to copy next 4K from EEPROM.. is there any pre-defined routines available to copy it to RAM? Can anyone help me in solving this problem? Thanks and Regards Chandrasekhar

TI showing example of secondary bootloader to copy code from Flash to SRAM and SDRAM. It seems that the code copy word by word from flash to SRAM and SDRAM. Isn't it more efficient to use DMA to move big blocks. How does one do this if DMA is to be used instead of copying word by word. ;* ------------------- File: boot.asm ------------------------------- ----* .title "...

Hi, Ie have try to make it hundred of times but without success. After reading the TI's PDF (spra999a.pdf) I wrote the bootloader without DSP/BIOS and it is running ok. Unfortunately it is not the same with the BIOS version. The first 1k is well copied into the internal ram. The copy table is read properly and all sections are placed where they have to be. But when the DSP jump to the ent...

Dear all, We get a problem about c6416 flash burn and bootloader, I can nearly grasp the corresponding process by reading spra999a, but I am not good at the linear assembly language, all my implemention program is written in C. so, I can't be sure about bootloader code. And I can't find the code in TI (only 67), I would be very app

Hi I'm trying to build a project that programmed in flash by flashburn with C6713. For this case, I followed SPRA999A1 in my project. But it is not successful. For example error is "Flash_boot and Flash_boot in page 0 have overlap." I couldn't find its reason. Also: I opened an example of SPRa999a1.Zip file then I delete source files and add my source files and a bootloader code. CCS ...
