Software Development +Platform(RPXlite DW),which has a NEC NL6448BC20-08 LCD panel. + +It has the following three features: + +1. 64MHz/48MHz system frequence setting options. +The default setting is 48MHz.To get a 64MHz u-boot,just add +'64' in make command,like + +make RPXlite_DW_64_config +make all + +2. CFG_ENV_IS_IN_FLASH/CFG_ENV_IS_IN_NVRAM + +The default environment parameter is stored in FLASH because it is a common choice for +environment parameter.So I make NVRAM as backup parameter storeage.The reason why I +didn't use EEPROM for ENV is that PlanetCore V2.0 use EEPROM as environment parameter +home.Because of the possibility of using two firewares on this board,I didn't +'disturb' EEPROM.To get NVRAM support,you may use the following build command: + +make RPXlite_DW_NVRAM_config +make all + +3. LCD panel support + +To support the Platform better,I added LCD panel(NL6448BC20-08) function.But bewear of +the fact that once you build this support and program it to FLASH,you should make sure +you put workable kernel and ramdisk at the right place in FLASH or through NFS. +Otherwise, you must erase this fireware manually via BDI2000 or ICE tools.So this +function is used for deployment and demo only.Pls look before you leap. + +To get a LCD support u-boot,you can do the following: + +make RPXlite_DW_LCD_config +make all + +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The basic make commands could be: + +make RPXlite_DW_config +make RPXlite_DW_64_config +make RPXlite_DW_LCD_config +make RPXlite_DW_NVRAM_config + +BTW,you can combine the above features together and get a workable u-boot to meet your need. +For example,to get a 64MHZ && ENV_IS_IN_FLASH && LCD panel support u-boot,you can type: + +make RPXlite_DW_NVRAM_64_LCD_config +make all + +So other combining make commands could be: + +make RPXlite_DW_NVRAM_64_config +make RPXlite_DW_NVRAM_LCD_config +make RPXlite_DW_64_LCD_config + +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The boot process by "make RPXlite_DW_config" could be: + +U-Boot 1.1.1 (Jun 8 2004 - 11:16:30) + +CPU: PPC823EZTnnB2 at 48 MHz: 16 kB I-Cache 8 kB D-Cache +Board: RPXlite_DW +DRAM: 64 MB +FLASH: 16 MB +*** Warning - bad CRC, using default environment + +In: serial +Out: serial +Err: serial +Net: SCC ETHERNET +u-boot> + +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +I'd like to extend my heartfelt gratitute to kind people for helping me work it out. +I would particually thank Wolfgang Denk for his nice help. + +Enjoy, + +Sam Song, samsongshu@yahoo.com.cn +Institute of Electrical Machinery and Controls +Shanghai University + +June 8,2004 diff --git a/board/RPXlite_dw/RPXlite_dw.c b/board/RPXlite_dw/RPXlite_dw.c new file mode 100644 index 0000000..86cf6c1 --- /dev/null +++ b/board/RPXlite_dw/RPXlite_dw.c @@ -0,0 +1,180 @@ +/* + * (C) Copyright 2004 + * Sam Song, IEMC.
