Boot Mode Selection

The bootmode for the AM263Px is selected by a DIP switch (SW6) or the test automation header. The test automation header uses an I2C IO expansion buffer to drive the bootmode when PORz is toggled. The supported boot modes are as shown in Table 2-4.

Table 2-4 Supported Boot Modes
Boot Mode/Peripheral Boot Media/Host Notes
QSPI(4S), 50MHz Flash Memory ROM configures OSPI controller in QSPI 4S mode and downloads image from external flash, supports UART fallback boot mode if any failures.
UART External Host ROM configures UART0 with baud rate of 115200bps and downloads image from external PC terminal using x-modem protocol.
QSPI(1S), 50MHz Flash Memory ROM configures OSPI controller in QSPI 1S mode and downloads image from external flash, supports UART fallback boot mode if any failures.
OSPI(8S), 50MHz Flash Memory ROM configures OSPI controller in 8S mode and downloads image from external flash, supports UART fallback boot mode if any failures.
xSPI (1S->8D) , 25MHz, SFDP QSPI Flash / External Host ROM configures OSPI controller in xSPI 8D mode ,Reads SFDP table for read command and downloads image from external flash, Flashes with SFDP are of JEDEC standard Rev D only supported.
DevBoot N/A No SBL. Used for development purposes only.
