Hey @Tim Edwards! Do you know why when I write the two following matrices to the wishbone bus, the controller writes up messed up values? int32_t avals [] = { -3, -15, -6, 7}; int32_t bvals [] = { 9, -15, -2 -5}; Writing -3, to 31000018 Writing -15, to 3100001c Writing -6, to 31000020 Writing 7, to 31000024 Writing 9, to 31000028 Writing -15, to 3100002c Writing -7, to 31000030 Writing -3, to 31000034 It should be -2 and -5 NOT -7 and -3!
