From abfb0596ba63f83a511f797b668b1ecf5de8fca6 Mon Sep 17 00:00:00 2001 From: Steven Shiau Date: Mon, 17 Jun 2019 15:09:21 +0000 Subject: [PATCH] A workaround to make sure /dev/mtd0 can be created A workaround to make sure /dev/mtd0 can be created when memdisk is used. This is due to sometimes "modprobe phram" can not successfully create /dev/mtd0. Have to try several times.
