Hi Wolfgang,

I am Arun, new in U-Boot, I have some queries regarding U-Boot, and to get the answers I sent a mail on Aug. 17, 2007, but that mail is not listed in mailing list.
But when I am searching for that mail using particular string, I found that.
Can I know why this happen, and not included in list?

So, Again I am resending same mail.

Hi,

I am new to U-Boot. Currently I am working for adm5120 board.
I read "readme" file, and "DULG.pdf", & U-Boot mailing archive also.

ADM5120 / ADM5120P
Specs:

    * 175MHz/227MIPS 4Kc CPU with an embedded cache, 8K-byte I-cache and 8K D-cache MIPS32
    * 5 IEEE 802.e Fast Ethernet PHY interfaces and 1 GMII/MII interface
    * Two SDRAM banks (each bank 1M-32 up to 32Mx32Bit)(support upto 2Mx32Bytes)
    * Two Flash banks up to 4MB(NOR Flash and Nand Flash), and many more.

I have few questions regarding this, are

My "config.mk" file contains
   #ROM version
   TEXT_BASE = 0x80100000
   PRE_TEXT_BASE = 0xBFC00000

Q1: TEXT_BASE is the location of U-Boot in RAM, means TEXT_BASE points to SDRAM perticular location? or tell more about TEXT_BASE.
Q2: In my board setting CFG_MONITOR_BASE=TEXT_BASE, means my boot monitor code reading from EEPROM?
*****************************
For my board setting
#define CFG_SDRAM_BASE             0x80000000    and
#define CFG_MEMTEST_START    0x80100000
#define CFG_MEMTEST_END          0x81000000

Q3: CFG_MEMTEST_START, and CFG_MEMTEST_END are simple memory test area, but I don't understand purpose of this test or which test and purpose?
*****************************
In my board setting
/* addresses for switch descriptors and buffers
* reason for those fixed address is that the adm5120 switch
* engine can only deploy descriptors and packet buffers
* @ address < 16MB.
* 0x80000000 ~ 0x80100000 is now reserved, so it SHOULD be safe
* to put the addresses within this area
*/
#define CFG_PKTBUF_ADDR         0x800C0000
#define CFG_ARPBUF_ADDR         0x800D0000
#define CFG_DESC_ADDR           0x800F0000
Q4: means?

Q5: Which are the other important configuration macro's I've to study? or I've to pay more attention?

Q6: Where I get more help of U-Boot for ADM5120, excepts the above mentioned files?

Thanks
