SPI SREC Bootloader

[revital.l]

Hi,

This bootloader is working for me.... but I works very slow (takes 7 seconds)

How can I accelerate it?

I heard there is a dividor in the spi driver - how can I change it?

Thanks Alot,

Revital

SW can change it through XQspiPs_SetClkPrescaler function 

But we don't use spi ps but axi spi....

There is no appropriate function for that....

Thanks,

Revital

Change type of bootloader.

Use a "Binary" bootloader instead of "SREC".

I am using a template project

There is no binary bootloader in the templates only SREC

Thanks,

Hi, revital.l:

             How did you solve this problem ?  I also met this problem, my boot period is more than 32s.

This one is way faster:

write the elf file in your flash as it is (not in SREC format). From eb-config.h choose the base address of your elf file. You might want to change SPI_READ_OPERATION and SPI_FLASH_NDUMMY_CYCLES parameters depending on the flash setup you are using.

Btw, it is not mine, I just want to put it in here so that people with this problem can reach it easily.

Do you have 

#define VERBOSE 

in your bootloader.c file?

I found that commenting out/removing that line will make the bootloader run faster.
