Thanks to Michal - in the u-boot-xlnx/master-next (vs /master) the following
lines were removed:
board/xilinx/zynq/board.c:
- /* temporary hack to take USB out of reset til the is fixed
- * in Linux
- */
- writel(0x80, 0xe000a204);
- writel(0x80, 0xe000a208);
- writel(0x80, 0xe000a040);
- writel(0x00, 0xe000a040);
- writel(0x80, 0xe000a040);
This is board-specific (but the same for zedboard & microzed) USB reset
wired to MIO7. Without these lines USB reset stays active.
Thanks
