SD/MMC card slot hot-plug issue SD/MMC card slot can't support hot-plug, the SD card can only be identify if it was pluged into slot before system boot. After check the code of arago git, it seems the gpio part wasn't enabled since I found the gpio_bank_count is zero in arch/arm/plat-omap/gpio.c, I want to add gpio bank support in the file, however I can't find gpio base address in AM389x Sitara ARM Microprocessors (MPUs) Technical Reference Manual. 2. SATA interface issue SATA disk only works well if connect with SATA0/J12, the disk can't be recognize if connect with SATA1/J11. Does anyone has some hints for these? Thanks in advance!
