I am getting a syntax error when I try to load multiple dtbo files.
It works properly when I load only BB-UART4-00A0.dtbo by adding the
following lines:
setenv fdt_buffer 0x60000; \
load mmc 0:1 ${rdaddr} /lib/firmware/BB-UART4-00A0.dtbo; \
When I add multiple dtbo files as you have shown in the example I get a
syntax error.
