Tool/software: Linux
Hello,
We are using the AM3352 on a custom board running Linux 4.9 built from the sources in the TI processor SDK 04.02.00. We were originally using a Micron eMMC p/n MTFC16GJDDQ-4M IT (JEDEC/MMC 4.41) which worked correctly with the eMMC driver supplied with the kernel. Due to obsolesence, the eMMC was replaced with Micron p/n MTFC16GAKAENA-4M IT (JEDEC/MMC 5.0). With the new eMMC, when the kernel boots and attempts to initialize the eMMC, the follwing is output and the boot process halts:
mmc0: error -110 whilst initialising MMC card
It appears that the calls to mmc_switch in mmc_select_bus_width as well as the call to mmc_switch to enable HPI in mmc_init_card (both located in mmc.c) are returning -110 (-ETIMEDOUT) which is causing mmc_init_card to return -110 and thus the mmc initialization fails.
The relevant device tree entries for the mmc are as follows:
mmc2: mmc@481d8000 {
compatible = "ti,omap4-hsmmc";
ti,hwmods = "mmc2";
ti,needs-special-reset;
dmas = <&edma 2 0
&edma 3 0>;
dma-names = "tx", "rx";
interrupts = <28>;
interrupt-parent = <&intc>;
reg = <0x481d8000 0x1000>;
status = "disabled";
};
&mmc2 {
vmmc-supply = <&vmmc_reg>;
pinctrl-names = "default";
pinctrl-0 = <&emmc_pins>;
bus-width = <8>;
ti,non-removable;
non-removable;
wp-gpios = <&gpio1 28 GPIO_ACTIVE_LOW>;
ti,needs-special-hs-handling;
status = "okay";
};
The complete kernel boot log is attached.
Any suggestions? Thank you.
