Here's what I did instead: lftpget ftp://ftp.parallella.org/parallella/sd_images/BOOT.ZedBoard_E16.bin od -Ad -tx1 BOOT.ZedBoard_E16.bin | fgrep -1 '99 aa' dd if=BOOT.ZedBoard_E16.bin bs=68392 skip=1 of=bitstream-zed-201307.bin dd of=bitstream-zed-201307.bin bs=4045564 count=0 seek=1 Then as root: umask 077; mknod /dev/xdevcfg c 259 0 cat bitstream-zed-201307.bin > /dev/xdevcfg Now the new eSDK's matmul example works fine. :-) Of course, we'll be back to the previous bitstream when the system reboots, unless we replace BOOT.BIN. I'll probably try that later. > I wonder if our inconsistent eSDK and BOOT.BIN versions may be causing > any trouble for the bcrypt code as well. Probably not. Katja - please re-run your bcrypt on Epiphany tests now. If the system reboots and you want the new official bitstream loaded again, you may re-issue the mknod and cat commands above. The bitstream is in: root@...aro-ubuntu-desktop:~/201307# ls -l total 8180 -rw-r--r-- 1 root root 4045564 2013-08-14 13:12 bitstream-zed-201307.bin -rw-r--r-- 1 root root 4327092 2013-07-17 01:44 BOOT.ZedBoard_E16.bin And yes, I haven't yet tried the files that Sylvain provided to us. I should. I was simply distracted to other matters (and still am). Alexander
