3.4.4 Configuration
3.4.4.1 Boot Modes
The boot mode for the AM64x EVM is defined by either a bank of switches
SW2
and
SW3
or by the I2C buffer
(
U96
) connected to the test automation connector (
J38
). All the boot mode pins have a weak pull-down resistor
and a switch capable of connecting to a strong pull up resistor. Switch set to “ON” corresponds to logic “HIGH”
while “OFF” corresponds to logic “LOW”.
For a full description of all AM64x SoC supported bootmodes, see the
AM64x Sitara™ Processors Data Manual
AM64x Processors Silicon Revision 1.0 Texas Instruments Families of Products Technical Reference
.
The following boot modes are supported by EVM:
1. OSPI
2. MMC1 - SD Card
3. MMC0 - eMMC installed
4. USB - boot using host mode with bulk storage. USB 2.0 mass storage using FAT16/32 (i.e. thumb drive)
5. USB - device boot DFU
6. UART
7. No-Boot
