Make the following change to run the Python bootloader loading script to make it read the entire binary in Windows:</p> <p>data = map(lambda c: ord(c), file(args[0]).read())<br /> -&gt;<br /> f=open(args[0], mode='rb')<br /> data = map(lambda c: ord(c), f.read())</p> <p>in DOS, this input<br /> C:\Python27\python.exe stm32loader.py -p COM5 -evw maple_RET6_boot.bin<br /> Produced the following output(some parts skipped):<br /> Bootloader version 22<br /> Chip id `['0x4', '0x10']'<br /> Write 15744 bytes<br /> Write 256 bytes at 0x8000000<br /> ...<br /> Write 256 bytes at 0x8003D00<br /> ...<br /> Read 256 bytes at 0x8003D00<br /> Verification OK</p> <p>Still not actually working, though (usb not connecting to PC on reset like it used to before I started trying to reload the bootloader). </p> http://forums.leaflabs.com/topic.php?id=9232#post-20370 Fri, 19 Oct 2012 15:04:20 +0000 dsoodak 20370@http://forums.leaflabs.com/ <p>Update: Evidently, the python "read" function, when implemented in Windows, interprets "0x1A" as EOF. I suppose the workaround is a more suitable question for a Python board, but I will post the results here in case anyone else tries to do this in Windows. </p> http://forums.leaflabs.com/topic.php?id=9232#post-20369 Fri, 19 Oct 2012 14:31:15 +0000 dsoodak 20369@http://forums.leaflabs.com/ <p>Update: The problem is that python refuses to read the whole file. Maybe because it was compiled in a linux environment so it thinks it sees EOF?</p> <p>I added "open(args[0], 'rb')" before<br /> "data = map(lambda c: ord(c), file(args[0]).read())",<br /> then tried<br /> "data = map(lambda c: ord(c), file(args[0]).read(os.path.getsize(args[0])))", but it is still only reading 486 bytes even though os.path.getsize() returns 15744 bytes. </p> http://forums.leaflabs.com/topic.php?id=9232#post-20345 Thu, 18 Oct 2012 20:15:39 +0000 dsoodak 20345@http://forums.leaflabs.com/ <p>Following the instructions on <a href="http://leaflabs.com/docs/bootloader.html" rel="nofollow">http://leaflabs.com/docs/bootloader.html</a>:</p> <p>C:\Python27\python.exe stm32loader.py -p COM5 -evw maple_RET6_boot.bin<br /> Bootloader version 22<br /> Chip id `['0x4', '0x10']'<br /> Write 256 bytes at 0x8000000<br /> Write 256 bytes at 0x8000100<br /> Read 256 bytes at 0x8000000<br /> Read 256 bytes at 0x8000100<br /> Verification OK</p> <p>For some reason it only wrote 512 bytes of the file(I downloaded the pre-compiled binary from the website)...any idea what would cause this?</p> <p>I'm using WindowsXP, Python 2.7, py-serial 2.6, and have the Maple Rev5 board. </p>
