BOOT COMMANDS
The boot commands provide facilities for booting application programs and operating sys-
tems from various devices.
bootbus
The bootbus command allows you to boot an application program over a bus interface.
Definition:
bootbus
bootbus uses the
busmagicaddr
field from the NVRAM environment parameters as the base
address of a shared memory region. This region contains two 32-bit (unsigned long) values,
in the form:
struct BusComStruct
{
unsigned long MagicLoc;
unsigned long Call Address;
}
The first is used for synchronization, and the second is the entry address of the application.
The sequence of events used for loading an application is described below:
1
The host board waits for the target (this board) to write the value 0x496D4F6B (character
string “ImOk”) to MagicLoc to show that the target is initialized and waiting for a download.
During initialization, the target loads the contents of its
loadaddr
environment parameter
into CallAddress.
2
The host board downloads the application to the target board. The host board can choose
to use the start address specified in CallAddress, or it can download the application to a new
location and write this new start address to CallAddress.
3
The host board finally writes 0x596F4F6B (character string “YoOk”) to MagicLoc to show
that the application is ready for the target.
4
The target writes value 0x42796521 (character string “Bye!”) to MagicLoc to show that the
application was found. If necessary, the target then updates its memory-resident
loadaddr
