Hi everyone,
I have a question about the operation when I want to transfer more than 4KB of data from EEPROM at boot time.
There is the following description in reference manual after copying 4KB of data from EEPROM to internal RAM by the boot ROM code.
6.1.5.5.1 Serial(SPI) NOR eFUSE configuration
After a successful DCD extraction, the ROM code
extracts the destination pointer and length of image from the Boot Data Structure to be
copied to the RAM device from where the code execution occurs.
6.1.5.5.2 ECSPI boot
If the DCD verification is successful, the ROM code copies the initial 4 KB of data, as
well as the rest of the image extracted from the application image, directly to the
application destination.
Question)
The information contained in the initially transferred 4KB data is analyzed, and the portion exceeding 4KB is automatically copied.
Am I correct ?
