From http://processors.wiki.ti.com/index.php/BIOS_MCSDK_2.0_User_Guide#Booting_and_Flash, it is stated
"The POST application resides on the EEPROM of the EVM, therefore the size of the image has to be less than 32 KB."
The size of the EEPROM on the EVM is 1Mb => 128MB. The EEPROM is divided into 2 sector 0x50 and 0x51. So why is the maximum size of the image 32kB and not 64kB?
