Re: GDB Problem

Andrew
    Thank you so much for taking the time to reply me, follow you direction, I use serial port to connect boards,
in gdb mode I type:
"(gdb) set remotebaud 115200"
"(gdb) target remote com1"
but some error show me:
"Remote debugging using com1"
"couldn't establish connection to remote target"
"cannot access memory at address 0xcca7cd2a"

Please give me a hand!

Thank you!

Henry,
Sincerely

Does your serial cable work OK? 

try doing

set remotedebug on

and see if there is any communication between the host and the target.

hmm...not sure whether you did that, but did you set a breakpoint? at 
least from the summary above it looks like you didn't...

Re: ISR to DSR delay?

Hi,

Progress update:

I'm still searching, but find a strange thing: In the irq_end routine 
(intr.cxx:323) there's a Cyg_Scheduler::unlock(), which should run pending 
dsr's. I think there're to possible things which this function could to:
Decrease the scheduler lock and return and Decrease and call unlock_inner() 
to call pending dsr's. What i see is that this ::unlock() take sometimes 
more than 6ms, but the unlock_inner() is always fast (some microseconds). 
So what could be the cause? Maybe a context switch while unlocking? Any 
hints?

Bye...

Re: Serial support for arm board

No, but even if I had would that have not been cleared
with a reboot?

no, GDB will set the breakpoint on loading. so, if you staid connected, 
did a reset of the board and then reloaded the image, you'd end up with 
the breakpoint set again.

what i usually do is set breakpoints at cyg_user_start and 
cyg_assert_fail before doing the continue.

It does :-)  Currently at 5,658,576 tests executed and counting with
results easily searchable and selectable by our engineers.

OOI, while the docs refer to dejagnu, while at Cynus and later planet
Red Hat, it became clear to us that while dejagnu is fine for driving
gcc and gdb tests, unfortunately it does not cut the mustard when it
comes to driving eCos tests. Generally, we have found that the
configtool testing capability fulfils the requirements of most
developers whose use anoncvs so have not taken that further.

As for our test farm, eCosCentric have spent a significant amount of
effort and investment developing a fully-automated eCos testing
infrastructure to help us produce eCosPro. It puts eCos through its
paces in ways that the configtool cannot but requires a similar

sntp question

I have been looking at the sntp code in eCos.

In the docs it talks about starting the sntp thread automatically if the 
dhcp server includes information about ntp servers. I have searched the 
source and I can't find any code that does this.

Are the docs correct and if so where is the code?

Thanks,

Will

Problem building from anon CVS

Hi, 

I’m having problems building with the latest code I downloaded from the anon
CVS. Previously I used the very old code & utils that were included in
Massa’s book. I simply wanted to get acquainted with eCos following his
tutorial. Next I grabbed the latest from the repository and using the eCos
Config tool v2.11 can no longer build. I get the following error:

/ecos-c/ecos/packages/hal/i386/pc/current/src/plf_misc.c: In function
`hal_platform_init':
/ecos-c/ecos/packages/hal/i386/pc/current/src/plf_misc.c:129: parse error
before `lo'
/ecos-c/ecos/packages/hal/i386/pc/current/src/plf_misc.c:131: `lo'
undeclared (first use in this function)
/ecos-c/ecos/packages/hal/i386/pc/current/src/plf_misc.c:131: (Each
undeclared identifier is reported only once
/ecos-c/ecos/packages/hal/i386/pc/current/src/plf_misc.c:131: for each
function it appears in.)
/ecos-c/ecos/packages/hal/i386/pc/current/src/plf_misc.c:132: `hi'
undeclared (first use in this function)

I’ve searched the mailing list with no luck and I apologize if this was
explained and I missed it.  I’m running on a WINXP platform with a recent
version of cygwin I just downloaded. Any thoughts as to what is going wrong?

This looks like a problem with setup - are you sure you're not
getting any other errors/warnings before this?  In particular,
this error says that the eCos standard type "cyg_uint8" is not
defined, which would imply that there was a problem including
