6.2.1.4.2 Environment Variables Passed to the GPP
The SPP passes information to the GPP in the first 512 bytes of the FPGA shared memory area.
The format of this shared memory area is:
z
Bytes 0/1 form the length code <len> (Byte 0 is the lsb, byte 1 the msb)
z
Bytes 2 .. <len>+1 contains the parameter information. Parameters are passed as zero-
terminated <name>=<value> ASCII strings. The last parameter string is terminated with
two zero bytes.
z
Bytes <len> + 2 (lsb) and <len>+3 (msb) contains the checksum over the parameter
information.
U-Boot initializes the parameter area with the following name/value pairs before releasing the
GPP from reset):
