Hi Everyone, 

 
We have used the example program taken from path
“C:\Keil\ARM\Boards\Keil\MCB2300\RL\FlashFS\SD_File\SD_File.uV2”
to create a file in MMC card interfaced to LPC2368 microcontroller
using MMC card bus (Native mode). The code is working</description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: SD/MMC card init failed</title><link>https://community.arm.com/thread/80234?ContentTypeID=1</link><pubDate>Fri, 11 May 2012 05:10:07 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:afc27871-f1db-4149-a700-4924a7780377</guid><dc:creator>surender reddy</dc:creator><description>&lt;p&gt;&lt;p&gt;
HI, Everyone I have got one more problem at present we are working
with 1GB MMC card we want the MMC card insertion to be hot
plug-gable. For this we have used one GPIO pin to detect insertion of
the MMC card. But when the MMC card is inserted my system(LPC 2368
controller) is resetting. Please help me i want my system with MMC
card support to be hot pluggable. Please Reply me.&lt;/p&gt;

Hi michael tscharntke&lt;/p&gt;

&lt;p&gt;
Thanks for your reply, I think whether the sample code from RL
library which i have taken works only for micro-SD cards not the
micro-SDHC cards. Is that the reason Please reply me.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: SD/MMC card init failed</title><link>https://community.arm.com/thread/80235?ContentTypeID=1</link><pubDate>Fri, 11 May 2012 04:54:52 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:bab30e71-c8e6-4974-8473-f173efcc8003</guid><dc:creator>surender reddy</dc:creator><description>&lt;p&gt;&lt;p&gt;
HI mhsn rah&lt;/p&gt;

&lt;p&gt;
I have formatted the 4GB card in PC with FAT32 file system and
There is no chance of formatting with the sample code listed because
it is not recognizing by MMC card.&lt;/p&gt;

&lt;p&gt;
Thanks for your reply mhsn rah&lt;/p&gt;

Hi Neda,&lt;/p&gt;

&lt;p&gt;
Try to format your card with FAT32 and 512-bytes allocation unit
size,&lt;br /&gt;
it may help.&lt;/p&gt;

Depending on sw versions the rl lib mci_lpc2368 has some timing
Problems realized using simple &amp;quot;for&amp;quot; loops. Just increase the loops
endvalues will help as workaround for most sd-Cards.&lt;/p&gt;

NO! don&amp;#39;t just sit there - get &lt;b&gt;debugging&lt;/b&gt;!&lt;/p&gt;

&lt;p&gt;
Or, if you want support from Keil, you need to contact them
direct.&lt;/p&gt;
