We have a custom carrier board which is running on T30 SOM. For our required i want to configure “TEGRA_GPIO_PV3” GPIO (whcih default configured for “MMC1_CD_N” with 171 GPIO number) as an interrupt. So to configure the TEGRA_GPIO_PV3 have disabled the EMMC from the kernel menuconfig. Please find the attached screeshot (EMMC_Menuconfig).
After flashing the EMMC disabled kernel, board is not booting (waiting for the EMMC device) and getting hung with the message “Waiting for root device /dev/mmcblk0p2…”
Please find the attached kernel config changes (EMMC_Menuconfig) to disable the EMMC and the boot up logslink text.
So is there any other place to completely disable the EMMC?
Note: Below are the hardware and software setup details:
1)hardware :- T30 SOM + custom Carrier board
2) Software versions :- Linux apalis-t30 3.1.10
