Subject: [ECOS] memory layout tool
Date: Sun, 03 Jul 2005 23:00:00 -0000 [thread overview]
Message-ID: <BAY106-F254320273E5AA8711F714D4E40@phx.gbl> (raw)
Hello,
I am working on porting redboot, and eventually ecos, to my arm7tdmi based
platform. I am following the hal-porting-platform.html documentation. On
step 4, adjusting the MLT files, I am running into problems:
The docs suggest that I use the Memory Layout Tool (MLT) in Configtool.
Supposedly it is in a separate window, but I do not see this window.
Searching around a bit, it appears that the MLT doesn't exist in Configtool
2 (looks like this is what I have, but I can't be sure -- going to Help ->
About I see "eCos Configuration Tool 2.net". Why the .net?)
I am now trying to configure the files by hand. Looking at
mlt_arm_platform_rom.ldi, I'm not sure what much of the syntax in SECTIONS {
... } refers to. Here are some questions:
1. The arm exception vectors are at 0x0 to 0x20, but I see
SECTION_rom_vectors (rom, 0x0, LMA_EQ_VMA). Does this refer to the virtual
vectors or the arm exception vectors?
2. What does LMA_EQ_VMA mean?
3. What is SECTION_got used for?
4. What is SECTION_fixup used for?
...
I suppose what I am really asking is where can I find documentation on
precisely how to edit the .ldi and .h files by hand?
Cheers,
Chris
