Dear all:
I use OAMPL137 and want to boot from NAND flash, try to build the ARMUBL/DSPUBL from PSP. I follow the steps as wiki: "GSG:Building Software Components for OMAP-L1/AM1x" said. The program/source are:
1. CCS: Version: 4.2.1.00004
2. ARMUBL/DSPUBL source codes come directly from "REL_LSP_02_20_00_07/PSP_02_20_00_07/board_utilities/armubl (dspubl)"
3. Import armubl project by select from ccs "Project->Import Legacy CCSv3.3 project"
4. Select menu "Project -> clean", "Project ->Rebuild all".
The questions are:
1. I got following warning messages after ARMUBL compilation, is it safe to ignore these messages or something I should setting?
warning window:
Severity and Description Path Resource Location Creation Time Id
creating output section ".const" without a SECTIONS specification ubl line 0 1299227456812 153

this assembly directive potentially unsafe inside a function ubl/src boot.c line 89 1299227456812 152
console window:

'hex470.exe' 不是內部或外部命令、可執行的程式或批次檔。
<above sentence means hex470.exe is neither internal, external command, executable or batch file>
2. I can't get the binary result "ubl-nand.bin", only get "ubl-nand.out". Are there some settings I miss?
3. If everything is fine, how do I convert ubl-nand.out into ubl-nand.bin, or it's binary fomrat already? Since the wiki says ARMUBL should be binary format?
extra questions as below:
4. The wiki said to use hexgen convert DSP ubl-nand.out into AIS format, by the command line tool
hexgen -romid D800K001 -seqread -crc 1 -spiclk 0 -appln <PATH to ubl-nand.out> -output <dsp-nand-ais.bin>
Is it D800K001 (or D800K003 depending on the omapl137 chip we have or no matter what oampl137 chip we have on hand ?
