<div>Hi,</div>
<div> </div>
<div>After applying below patches </div>
<div>kdb-v4.4-2.6.24-common-2.bz2</div>
<div>kdb-v4.3-2.4.20-xscale-1.bz2</div>
<div>and after bit of struggle I was able to enter the kdb prompt setting kdb=early flag on a OMAP3430 based target.</div>
<div> </div>
<div>Now I am trying other entry methods</div>
<div>a) Automatic entry when exception, divide by zero and NULL pointer derefernce happens</div>
<div> </div>
<div> For NULL pointer derefernce, I am calling the API kdb inside die() in file arch/arm/kernel/traps.c</div>
<div> But kdb behaviour here is not the same as in case of kdb=early entry; For ex: id command does not work ..etc</div>
<div> </div>
<div> Please let me know is this a correct way to proceed?</div>
<div> </div>
<div>b) Through key press <esc> KDB.</div>
<div> </div>
<div> I am not using the serial console driver; instead I am directly writing/reading from the low-level uart driver.</div>
<div> In this case how will the KDB come to know about the keypress.</div>
<div> As a workaround, I have an executable which will call a driver ioctl and inside the driver ioctl I am calling the API kdb()</div>
<div> Here also I am facing the same behaviour</div>
<div> [Note if I use the macro KDB_ENTER instead kdb() I get a bad memory address error in kdb_getarea]<br></div>
<div>Any clarifications as to whats missing/wrong will be very helpful</div>
<div> </div>
<div>Regards</div>
