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. ** Sent via the linuxppc-embedded mail list.
