Subject: Initialising eMMC: Card stuck in programming state! __mmc_switch
Date: Wed, 31 Aug 2016 11:56:40 +0200 [thread overview]
Message-ID: <57C6A9D8.6020705@phytec.de> (raw)
Hello,
I have a RK3288 based board with a Micron eMMC chip (MTFC16GAKAECN-4M
IT). This eMMC is EDEC/MMC standard version 5.0-compliant.
While doing eMMC boot tests with a 4.4.16 and 4.8.0-rc4 kernel I run
into the following problem after more than 100 cold resets:
[ 3.535448] dwmmc_rockchip ff0c0000.dwmmc: 1 slots initialized
[ 3.543823] dwmmc_rockchip ff0f0000.dwmmc: IDMAC supports 32-bit address mode.
[ 3.551276] dwmmc_rockchip ff0f0000.dwmmc: Using internal DMA controller.
[ 3.558206] dwmmc_rockchip ff0f0000.dwmmc: Version ID is 270a

The bootloader I am using has no problems with the eMMC as you can see
