I set the SCB-&gt;VTOR=0x8005000 or 0x20000C00 at the very beginning of main() and that did it so I thought this was missing from the bootloader. Alas, adding it to the bootloader didn't fix the problem, and it turned out that the ST library sets SCB-&gt;VTOR during SysInit (between bootloader and main). </p> <p>So there, setting this value correctly during the initialization will let you use Maple bootloader with dfu-util to load any binaries. </p> http://forums.leaflabs.com/topic.php?id=594#post-3288 Mon, 03 Jan 2011 21:50:25 +0000 ianmga 3288@http://forums.leaflabs.com/ <p>Where in the bootloader or the library is the vector table pointer (SCB_VTOR) set to the actual vector table? I can't find it anywhere. </p> http://forums.leaflabs.com/topic.php?id=594#post-3281 Sun, 02 Jan 2011 17:38:58 +0000 ianmga 3281@http://forums.leaflabs.com/ <p>Is it possible to use the Maple bootloader to load non-libmaple binaries?</p> <p>I am building (after porting) the ST library examples with Keil into binaries and load them to 0x80005000 with the Maple booloader and dfu-util. The basic blinky light works but the UART one does not when I enable RX interrupts. However, when I target it to 0x80000000 and flash it with the serial bootloader the UART example works fine, so my guess is that I am doing something wrong with the interrupt vector table.</p> <p>Is there something special about the way the bootloader handles the vector table or does it look like it's something on my side (very possible!)? </p>
