Yes, according to Peter, the failure comes only during the second call
to get_board_value()

I think the patch below should fix it:

diff --git a/board/udoo/neo/neo.c b/board/udoo/neo/neo.c
index 62f81fff6817..075c4f208f23 100644
--- a/board/udoo/neo/neo.c
+++ b/board/udoo/neo/neo.c
@@ -333,6 +333,8 @@ static int get_board_value(void)

*/

+ gpio_free(IMX_GPIO_NR(4, 13));
+ gpio_free(IMX_GPIO_NR(4, 0));
return (r184 << 1) + r185;
}

Thanks
