Bootloader

Hi Raam,

We understand that you are looking for booting using Second stage loaders (SSL). Please confirm if our understanding is correct.

The SSL is a stand-alone application that is executed at boot time before the actual application is dynamically loaded into memory. The SSL can be used to invoke a ROM API to boot a second application.

For detailed information, please refer the application note "EE-374: Implementing Second-Stage Loader on ADSP-BF707 Blackfin® Processors" which talks about Second-Stage Loader (SSL). The link is given below.

In this scenario, two push buttons are configured as GPIO inputs. These buttons determine which of the two separate applications to load from SPI memory by utilizing the adi_rom_Boot() function. Each application, identified by an offset in the SPI flash memory, will trigger either LED3 or LED4 on the board to blink.

Please take this as reference and modify it as per your requirement.

Additionally, we are attaching a simple SSL application example for ADSP-BF706 for your reference.
