U-Boot will check whether the GPP is in reset at startup. If this is the case, then:
z
The shared memory area in the FPGA is set up
z
The GPP is taken out of reset
z
u-boot waits until the GPP BIOS indicates "Runlevel 0 reached"
The "gpp" command can be used to control the gpp. It accepts the following options:
z
start <runlevel> [<timeout>]
Starts the GPP if it's in reset, waits until a runlevel > <runlevel> is reached. Aborts after
<timeout> seconds (default is 20).
z
restart
Same as start, but a GPP reset is enforced.
z
init
initializes the shared memory parameter area.
z
runlevel
Shows the current GPP runlevel
z
port80
Shows the last port-80 code written by the GPP BIOS.
z
show
Shows the current GPP status
z
set <name> [<value>]
Adds, removes or changes a parameter in the shared memory area.
6.2.1.4.1 GPP Run Levels
The GPP BIOS reports its boot progress via run level codes stored in mailbox register 0 of the
glue logic FPGA. The following run levels are defined:
