Hi all, 
i am facing one issue related to uart0 in keil MCB2300 board.i have
loaded .hex file into LPC2388 in MCB2300 board.After loading,removed
jumper int0 and rst(I am assuming these two are only for flashing.Is
it correct???).My program ( printing</description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: MCB2300 Issue</title><link>https://community.arm.com/thread/103588?ContentTypeID=1</link><pubDate>Wed, 04 Nov 2009 00:01:41 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:2cc1f150-60a9-41ba-8397-fd615f765d18</guid><dc:creator>ImPer Westermark</dc:creator><description>&lt;p&gt;&lt;p&gt;
Have you looked at the schematics?&lt;br /&gt;
&lt;a href="http://www.keil.com/arm/mcb2300/mcb2300-schematics.pdf"&gt;http://www.keil.com/arm/mcb2300/mcb2300-schematics.pdf&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;
What do you think happens if you have the ISP strap connected and
boot with the RS232 cable in, if the RS232 cable has the &amp;quot;wrong&amp;quot;
signal on the relevant handshake signal?&lt;/p&gt;

Manual says, After loading hex file,RST and INT jumpers should be
removed.&lt;/p&gt;

&lt;p&gt;
1. UART0 not communicating on following conditions:&lt;/p&gt;

&lt;p&gt;
removed jumper RST and INT0 ,Power cycle or reset, RS232 cable
connected to MCB-UARTo.&lt;/p&gt;

&lt;p&gt;
2. UART0 communicating on following conditions:&lt;/p&gt;

&lt;p&gt;
removed jumper RST and INT0 ,RS232 cable not connected to
MCB-UARTo on Power cycle or reset,then connected RS232 cable
connected to MCB-UARTo.&lt;/p&gt;

&lt;p&gt;
I have seen this issue with two keil MCB boards.&lt;/p&gt;

&lt;p&gt;
what i need to do on SW side or HW side for Condition-1 should
work???.&lt;br /&gt;
Tools used:&lt;br /&gt;
1. Flash magic for Flash .hex file&lt;br /&gt;
2. HT,Tera term for serila communication with terminal.&lt;/p&gt;

&lt;p&gt;
I am sure that there is no issue software side.this is some setup
issue.&lt;/p&gt;

&lt;p&gt;
Only Keil Team or anybody using Keil MCB boards can help me.&lt;/p&gt;

What does the &lt;b&gt;Manual&lt;/b&gt; tell you?&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: MCB2300 Issue</title><link>https://community.arm.com/thread/57191?ContentTypeID=1</link><pubDate>Tue, 03 Nov 2009 09:37:09 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:c94a4760-cea6-48ea-a477-24debecdb31b</guid><dc:creator>ImPer Westermark</dc:creator><description>&lt;p&gt;&lt;p&gt;
I haven&amp;#39;t the time to download the schematics for your board right
now.&lt;/p&gt;

&lt;p&gt;
But make sure that the straps are correct, so that the EINT0
signal is kept high when the processor is released from reset. If
this signal is low when you release the reset signal, then the
processor will enter the boot loader instead of starting your
program.&lt;/p&gt;

&lt;p&gt;
Depending on your strap settings, the RS232 port will be able to
control this signal, possibly ruining your day. The board has a
feature where FlashMagic may use RS232 handshake signals to control
reset and EINT0 to allow automatic programming, and this feature can
interfere.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
