Boot loader and firmware flashing on BF514F16

Hi,

Hi Divya,

Thanks for your reply, Here is my situation The .LDR bootloader and firmware  files that I have came from manufacturers website. I'm using ICE1000 as the programming device.

but when I tried to load the .ldr file to Visual DSP it's saying file is invalid or damaged. is this mean I need to have the bootloader and firmware in DXE format to flash this on the chip?

is there a way I can load the .ldr file  on visual DSP?

Thanks,

Hi Noliem,

Regarding "is this mean I need to have the bootloader and firmware in DXE format to flash this on the chip?"
>>>No, it's not possible to flash in DXE format to the chip.

Regarding "is there a way I can load the .ldr file  on visual DSP?"
>>>Yes, you can load .ldr format in flash.

We recommend to refer topic "V.  USING LOADER FILES" in the "Readme.txt" available in the below VDSP installation path which provide steps to program the .ldr file into flash
< VDSP installation path >\VisualDSP 5.1.2\Blackfin\Examples\ADSP-BF518F EZ-Board\Power_On_Self_Test\readme.txt

Please follow the steps and let us share the screenshots of error along with steps if you are facing any issues.

Hi Divya,

Thanks for your help, after reading and trials it finally make sense to me how to do it. but I'm having another issue which I don't understand what causes it.

when I programed the flash it does not do anything for 20 minutes the progress bar showing nothing and it will show a message Error: Failed erasing affective field when Erase affected  in pre-program erase option is chosen. see pic attached.  and when I chose Erase All, it will show Error: Failed erasing Flash, see pic attached.  it also showing error if I chose Erase Base on map. see pic attached.

If a choose No erase, it will work programming the flash, but I does not seems to be overwriting the old firmware. I put a new firmware in and after successful programed, it was still on the old firmware.

I'm using an Ice 1000 and connecting to a consumer product with Blackfin BF514F16 processor.  i used the BF518FEzFlashDriver_M25P16 as the loader.

Can they  put the processor core in Secure entry mode or secure mode? preventing  the flash to get erase?

any idea how to circumvent this issue?

Thanks,

Hi Noliem,

1) Since you are using custom board, please share the silicon revision of your board, and the flash part you are using?
2) Did you use the loader file from the manufacturer's website or created an simple application?
3) Is it possible to change the boot mode to '0' and then debugging the simple LED application. Then flash the simple LED application and check whether the error occurs during flashing.
