Is the flash external sd card? If ture, why BCT, MB1, MB2 are in flash?
Is the sysRAM the 266KB SRAM, then what is SDRAM and what its size is? What the difference between sysRAM and SDRAM? Why BCT and MB1 and some FW are loaded into sysRAM but MB2, TOS, and other FW into SDRAM?
IROM is 128 kb ROM, i.e. internal eeprom?
FYI,the attached pic. is a part of the tx2 boot flow.
