From 7a53fb40ca2f79cc3f2a0b7ab4d5e4d71d34119b Mon Sep 17 00:00:00 2001 From: Zoltan HERPAI Date: Fri, 4 Jan 2019 13:11:26 +0100 Subject: [PATCH] uboot-sunxi: disable AXP209 on Olimex A13 Olinuxino Disable the PMIC on Olimex A13 Olinuxino, as the SPL cannot set the core voltage correctly, which causes the board to freeze later at kernel if CPU throttling is enabled (see below). This will almost certainly kill the VGA output (which requires LDO3 to be set), but this is still a better option than to disable CPU throttling for all Cortex-A8 based devices.
