This file contains basic information on the port of U-Boot to IPHASE4539
|
||
|
|
(Interphase 4539 T1/E1/J1 PMC Communications Controller).
|
||
|
|
All the changes fit in the common U-Boot infrastructure, providing a new
|
||
|
|
IPHASE4539-specific entry in makefiles. To build U-Boot for IPHASE4539,
|
||
|
|
type "make IPHASE4539_config", edit the "include/config_IPHASE4539.h"
|
||
|
|
file if necessary, then type "make".
|
||
|
|
|
||
|
|
|

|
|

|
|
--------------------------
|
||
|
|
|
||
|
|
The following tests have been conducted to validate the port of U-Boot
|
||
|
|

|
||
|
|
|
||
|
|
1. Operation on serial console:
|
||
|
|
|
||
|
|

|
||
|
|
output appeared on the serial terminal connected to the 2.5mm stereo jack

||
|
|
$ cd <path>/u-boot
|
||
|
|
$ make IPHASE4539_config
|
||
|
|
$ make dep
|
||
|
|
$ make
|
||
|
|
$ cp -p u-boot.bin /tftpboot
|
||
|
|
|
||
|
|
Load u-boot.bin into the Flash memory at 0xffb00000.
