Why Freescale Sabre Smart i.MX6 Solo X SD2 slot do not detect SD card insertion / removal while SD3 does? 1. How SDIO detection works on i.MX6? First, we checked how the i.MX6 CPU detect SDIO card insertion / removal. Freescale i.MX6 Solo X Reference Manual (IMX6SXRM.pdf) Section 68.4.7 "Card Insertion and Removal Detection" says that; "The uSDHC uses either the DATA3 pin or the CD_B pin to detect card insertion or removal. When there is no card on the MMC/SD bus, the DATA3 will be pulled to a low voltage level by default" "When the DATA3 pin is not used for card detection (for example, it is implemented in GPIO), the CD_B pin must be connected for card detection. Whether DATA3 is configured for card detection or not, the CD_B pin is always a reference for card detection." Based on this description, It seems that DATA3 is used for card detection. But it isn't. 2. Implementation on Sabre i.MX6 SoloX We checked voltage on DATA3(PIN1) on both SD2 and SD3 slot when card is not inserted. Both were 3.3V. Neither SD2 nor SD3 DATA3 was "pulled to a low voltage level by default". Then, we checked CD pin. In the case of SD3, it was 3.3V when card is not inserted, then fall to 0V when card is inserted. That cause card detection. In the case of SD2, CD pin was all time 0V. Sabre i.MX6SX Schematic confirms that CD pin of SD2 slot is not connected to anywhere (see attached image). Sabre SoloX SD2 Sabre SoloX SD3 "CD(Card Detect)" is not a SDIO pin. SDIO has only 9pins, where 9 DAT2 1 DAT3 2 CMD 3 VSS1 (GND) 4 VDD 5 CLK 6 VSS2 (GND) 7 DAT0 8 DAT1 - CD (Card Detection) and WP (Write Protect) are function of SD slot connector, not function of SDIO bus. 3. Implementation on Sabre i.MX6Q We checked i.MX6Q Sabre Smart. Again, DATA3 (pin1) voltage was 3.3V both on SD2 and SD3. Schematic shows there are register pattern prepared to pull down DATA3, but both R549 on SD3 and R667 SD3 are not populated (DNP) as default. Sabre i.MX6Q SD2 Sabre i.MX6Q SD3 4. Conclusion From this we can infer that Freescale reference design (Sabre i.MX6Q and i.MX6SX) do not use DATA3 for SDIO detection, as it appears to have been described in the reference manual. Both Sabre i.MX6Q and i.MX6SX solely relies on CD(Card Detect) signal from SDIO connector. In the case of SD2 slot on i.MX6SX, CD signal is not connected to anywhere.There where unpopulated DATA3 pull-down register pattern prepared on Sabre i.MX6Q, but it is omitted from i.MX6SX. Which makes card insertion / removal detection on Sabre i.MX6SX SD2 slot difficult.

Typical applications are for Industry Control, Communications, HMI, Smart Healthcare, Internet of Things (IoT), etc. The MYD-Y6ULX development board is delivered with necessary cable accessories including one 12V/2A power adapter, one net cable of 1.5m length, one Micro USB cable, one 4G LTE antenna, one WiFi antenna and one product disk. I noticed that the MYD-6ULX board has one USB based Mini PCI-e interface for 4G module. MYIR has provided 4G antenna but the 4G module is only as an option. Measuring only 37mm by 39mm, the MYC-Y6ULX CPU Module is a highly integrated controller board for the MYD-Y6ULX development board populated on an expansion board which measures 105mm by 140mm and extend a rich set of peripherals through headers and connector like Serial ports, USB, Ethernet, CAN, Micro SD card, WiFi module, LCD, Touch screen, Camera, Audio as well as a Mini PCIe interface for optional USB based 4G LTE module. The function block diagram for the MYD-Y6ULX development board is show as below: We can see the hardware peripherals and interfaces from the image below: All the on-board components are placed on the top side of the board, we can see only some through-holes on the bottom side of the board. On the MYD-Y6ULX board, there is a 2.4G WiFi module which is based on Broadcom 43362 chipset. The WiFi module is connected to the board through SDIO interface and provides full function of 802.11b/g/n. Its antenna uses the SMA antenna interface reserved on the board. But please note if the MYC-Y6ULX CPU Module is using eMMC and the board will not support WiFi as the eMMC will reuse the same SDIO interface with WiFi module. On the MYD-Y6ULX board, there is a USB based Mini PCIe interface for 4G LTE module. MYIR has provided Linux driver and example for using Quectel EC20 LTE module on the MYD-Y6ULX board. So, if the EC20 4G LTE module can meet your requirement, you can take it as a priority to save development time. Near the Mini PCIe interface, there is a standard SIM card interface. There is one CSI interface, one expansion header and one Micro SD card interface near the Mini PCIe interface. Though the i.MX 6UL/6ULL processor can support up to 24-bit parallel camera interface, many signals have reused due to rich peripherals on MYD-Y6ULX board, so the CSI interface on MYD-Y6ULX is an 8-bit parallel camera interface. The expansion header can support 12 GPIOs at most to bring out I2C, UART, SPI, etc. There are two USB Host ports, Reset/Power/User buttons and one 3-pin debug header on the MYD-Y6ULX board. The i.MX 6UL/6ULL processor has two USB controllers, both of which can support USB OTG function. One MYIR’s MYD-Y6ULX board, one USB has brought out through Micro USB interface and can support OTG; another USB has extended 4 USB Host through SMSC USB2514BI-AEZ USB Hub chip, of the four USB Host, two are used as USB Host ports, one is used for 4G LTE module and the rest one is not used. The MYD-Y6ULX base board is designed to be powered by DC 12V through a jack, and the internal power management circuit on-board supplies 5V, ISO 5V, 3.8V, 3.3V, 1.8V, 3V (RTC) voltage for the board. The part TLV62130 DC/DC convertor is selected to use for 12V to 5V and 12V to 3.8V conversions, supporting 3A output currency at the most. The DC/DC convertor can increase the power efficiency and reduce power consumption of the board. The part RT9018 is used as LDO regulator for 5V to 3.3V and 3.3V to 1.8V conversions. The LDO regulator can provide smaller power ripple than the DC/DC convertor. The RTC battery input is an optional input. When the system is powered down, if the RTC does not need to work, it is not require to provide this power rail.
