9.16 Troubleshooting
To bypass the full board initialization sequence, attach a terminal to the console located on the
front of the ATCA-9305. Configure the terminal parameters to be:
9600 bps, no parity, 8 data bits, 1 stop bit
Reset the ATCA-9305 while holding down the ‘s’ key. Pressing the ‘s’ key forces a configuration
based on default environment variables.
9.17 Download Formats
The ATCA-9305 monitor supports binary and Motorola
®
S-Record download formats, as
described in the following sections.
pci_memsize
Sets the amount of SDRAM memory made available on the PCI bus. The
minimum setting is 16 megabytes. If not set, 128 MB of SDRAM are available
over PCI. This parameter takes a hex value.
Valid options: all, size in hex (0x8000000=128 MB)
pram
This memory region is at the very top of memory and can be reserved–not to
be cleared on start-up or reset. Default size of the protected memory region is
0. pram is defined in kilobytes and is a base 10 number. The smallest allowable
size is 4 (4 KB) and the largest recommended size is 32768 (32 MB). pram
should be 4 KB aligned, otherwise U-Boot will round pram to the next 4 KB
size.
sec_bootargs
Sets the boot arguments that are passed into the secondary application
images when using the bootv command. If not defined, bootv will pass the
bootargs configuration parameters into both the primary and secondary
application images.
shelf_addr
ATCA chassis shelf address provided by shelf-manager
Not defined in default configuration–reported at bootup from the IPMC
Table 9-7 Optional Environment Variables (continued)
Variable 1 Description
The moninit command does not initialize these variables. Each parameter is only defined if a change
from the default setting is desired and is not defined after initialization of the environment variables.
