Hi Marcos,<br>
<br>
Great news! I did not find any solution to the issue. I have a REV C board from element14. Is this the same board you are using? In my board I saw the issue.<br>
<br>
Does this have anything to do with the patch you submitted [PATCH] Beaglebone: fix missing clobber in inline assembly. <a href="https://lists.rtems.org/pipermail/devel/2015-September/012531.html" rel="noreferrer" target="_blank">https://lists.rtems.org/pipermail/devel/2015-September/012531.html</a><br>
I have not yet tested with this patch.<br>
<br>
The freebsd driver is working with cache disabled. If possible pls check if it is working with cache enabled in your board.<br>

<br></span>
If this is a board revision related issue, is there a way programmatically to<br>
know which revision the board is? That way the BSP could auto-detect the right<br>
thing to do. Otherwise, we may be looking at a BSP variant or a build option.<br>
I would rather avoid those if we can auto-detect.<br>

Hi Ragu,<br>
I wanted to know if you were able to see something else about the problem we had in the BBB when using LWIP and enabling cache ( the program freezes).<br>
I can tell you that here we were using BBB rev. A5C and had this problem, but now we could test this with a BBB Rev C, and it successfully works with cache enabled (using the same sdcard in both boards, one works and the other doesn't).<br>
Greetings<br>
