Is there any decision? And is there any difference in work on FLASH and RAM? </p> http://forums.leaflabs.com/topic.php?id=867#post-5255 Thu, 16 Jun 2011 11:44:38 +0000 poslathian 5255@http://forums.leaflabs.com/ <p>Check out this sweeeet video!<br /> <a href="http://www.youtube.com/watch?v=rvNIeKuXsxM" rel="nofollow">http://www.youtube.com/watch?v=rvNIeKuXsxM</a> </p> http://forums.leaflabs.com/topic.php?id=867#post-5253 Thu, 16 Jun 2011 10:55:14 +0000 poslathian 5253@http://forums.leaflabs.com/ <p>haha, for clarity, this should be changed to:</p> <p>"Press and release reset again, but this time press and hold the BUT button sometime during the few short blinks. You can release BUT once the slow blinks start. The slow blinking should continue forever, indicating perpetual bootloader mode"</p> <p>Incidentally, the only purpose of the first pressing of RESET is to get the user familiar with the blinking sequence. The concise instructions would just be: "press and release reset, immediately following, press and hold BUT until the slow blinks start" </p> http://forums.leaflabs.com/topic.php?id=867#post-5252 Thu, 16 Jun 2011 10:51:48 +0000 poslathian 5252@http://forums.leaflabs.com/ <p>This is a known bug that has not yet been cleared, unfortunately (beta product and all). I am nearly certain this bug stems from the fact that the RET6 uses 2KB flash pages, whereas the RBT6 uses 1KB flash pages. So the calls to dfu-util and the bootloader were modified for the RET6 to send data along in 2KB chunks rather than 1KB chunks. This is only for flash uploads, obviously.</p> <p>My guess is that the associated code in the bootloader for RAM uploads for some reason is not handling 2KB transactions gracefully (not sure why). There may be a fix for this without changing the bootloader, and just modding the call to dfu-util. </p> http://forums.leaflabs.com/topic.php?id=867#post-5251 Thu, 16 Jun 2011 10:21:34 +0000 gbulmer 5251@http://forums.leaflabs.com/ <p>I have two Maple RET6, and my old Maple rev3.</p> <p>There is a problem loading to RAM for the RET6.</p> <p>I use the Maple rev3 to check that the toolchain is working, and it seems to be.</p> <p>As a quick test of the RET6, I tried to upload blink using IDE 0.0.11.<br /> When I upload to "LeafLabs Maple RET6 Edition to Flash" it works, and the /dev/tty.usbmodemxxxx is visible in the Tools -&gt; Serial Port menu</p> <p>When I upload to RAM, the upload happens, but the LED doesn't blink, it stays off.<br /> Also the RET6 has disappeared from the Tools -&gt; Serial Ports menu.</p> <p>When I put the RET6 into perpetual bootloader mode (which sometimes takes several attempts, and I don't understand why, maybe the button has some manufacturing residue) the board reappears on the Tools-&gt;Serial Port menu<br /> It can again upload to Flash.</p> <p>When "LeafLabs Maple RET6 Edition to RAM" is selected, the upload appears to work (same sort of LED flashing), but the LED stays off, and the /dev/tty.usbmodemxxxx disappears from the menu.</p> <p>Put the board back into perpetual bootloader mode.<br /> It doesn't reappear on the Tools-&gt;Serial Port menu, but upload to Flash works, and runs.</p> <p>Both RET6 boards behave the same way. I can't load into RAM, only into Flash.<br /> Perpetual bootloader mode doesn't happen every time I press the buttons.</p> <p>Suggestions?</p> <p>Edit: I think the 6 quick flashes when the board can be put into perpetual bootloader mode may be a too bit quick. Please consider stretching it another second. </p> <p>Small point:<br /> (The instructions are a bit colloquial, does 'Hit' mean 'Click', i.e. quickly press and release? Or does 'Hit' mean even faster than 'Click', or something else? I think 'Click' is more universal, if that is what is meant. If 'Hit' isn't the same as 'Click' [which I don't believe] it might be helpful to spell out what 'Hit' means?</p> <p>Also, when I was taught English, we were taught to use 'but' rather than 'and' when some thing varied, e.g.<br /> "Hit reset again, and this time"<br /> would be<br /> "Hit reset again, but this time"<br /> to alert the reader that it is NOT the same as before.) </p>
