Hello.
My name is Cha.
I'm a newbie in this area, working on porting of linuxppc-embedded to HD860 board from http://www.headtel.com
Since I planned to use 8xxrom-0.3.0 as a bootloader, I read lots of pdf files related to MPC860 and FADS board.
After digging into 8xxrom code, I have many questions as follows.
--- Questions START.
1. What's the baud rate and serial port configurations of 8xxrom?
2. What's the meaning of ROMLOAD and DATA macros inf 8xxrom-0.3.0/Make.config
3. If ROMLOAD is base address of Flash ROM of FADS board why the value is 0xFE000000 neverthless the memory map of FADS board is as follows:
/* Memory map of FADS board from FADS user's manual
0x00000000 ~ : DRAM SIMM
0x02000000 ~ : Empty Space
0x02100000 ~ : BCSR~
0x02108000 ~ : Empty Space
0x02200000 ~ : MPC Internal MAP
0x02208000 ~ : Empty Space
0x02800000 ~ : Flash SIMM
0x03000000 ~ : SDRAM
0x03400000 ~ 0xFFFFFFFF : Empty Space
*/
4. I've found the sequence of image converting process is like that:
/* Image converting sequence of 8xxrom from Makefile
---> 8xxrom -> 8xxrom.elf -> 8xxrom.elf.s19
|
`----> 8xxrom.bin -> 8xxrom.bin.s19
*/
What's the difference between 8xxrom and 8xxrom.elf? (the disassemble result is same)
What's the difference between 8xxrom.bin and 8xxrom.elf?
Is bintos19 different from "powerpc-linux-objcopy -O srec" command?
Is mkrombin different from "powerpc-linux-objcopy -O binary" command?
5. Are there any documentation or README file for 8xrom or fads rom?
--- Questions END.
If these questions do not match with the subject of this mailing list, I'll apologize.
I'm sorry about my humble english. ;-)
Thanks in advance.
