Only Maple Native does, of the LeafLabs boards. Do you mean that you're using a Native? Or that you're using another chip with an FSMC?</p> <p>Other things seem strange. From your code:</p> <p><code>fsmc_nor_psram_set_addset(regs, 30);</code></p> <p>30 is suspiciously large, given that ADDSET is only 4 bits wide. The argument to <code>fsmc_nor_psram_set_addset()</code> is just ANDed with 0xF and shoved into the ADDSET bits directly (similarly for <code>fsmc_nor_psram_set_datast()</code>), so 30 can't possibly be what you mean. It looks like that value is just copy-pasta from your old code; I'd spend some more time looking at RM0008 to see what you really want to put into those bits. (Or just copy the values of the FSMC registers directly from the working code).</p> <p>Sorry that fsmc.h isn't very full-featured at the moment; it's mostly there to support the SRAM chip on Maple Native, so it's lacking when it comes to dealing with other sorts of memory. </p> http://forums.leaflabs.com/topic.php?id=1799#post-10870 Fri, 25 May 2012 15:14:53 +0000 blackswords 10870@http://forums.leaflabs.com/ <p>Hi, </p> <p>I want to port some code that I use with an LCD and the ST Library to Maple and I got stuck with the FSMC part.</p> <p>This is the old working configuration <a href="http://pastebin.com/R4sE2d5V">code</a>, someone can tell me how to replace it with the Maple functions? </p> <p>I tried <a href="http://pastebin.com/5TPtLt0K">this</a> but the MCU crash (a HardFault I think) after I tried to access to a register</p> <p>Thanks </p>
