Initialising eMMC: Card stuck in programming state! __mmc_switch

Initialising eMMC: Card stuck in programming state! __mmc_switch

[Wadim Egorov]

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.

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

Any hints on what the problem could be?

Is it produced with both 4.4.16 and 4.8.0-rc4?
Could you enable the CONFIG_MMC_DEBUG? And which mode do you use?

According to below bootloader log, you're using eMMC4.0 card, right?

yes, with both versions.

mode? Do you mean busmode? I am not sure. The eMMC runs with 50MHz, so I
think it should be SDR/DDR52 mode. Debug message below says busmode 2:

No, it is an eMMC5.0 card. The bootloader output seems to be wrong.

By looking up the emmc AVL for rockchip product line, we didn't test
this eMMC chip yet, so I couldn't say whether it's related to the buggy
eMMC firmware rather than host stack. But it looks more like a buggy
firmware from my debug experience. :)
