When I first got the SBC-EC9100 card, I was not very intensive. There are two main points. One is the British board, and I have never touch it. The interest is not big; the second is the main application processor or ARM Cortex-A7 In the impression, this is a bit can't keep up with the era. This idea may still be more influenced by the fast update of this mobile phone. It will attach this idea to other fields, see it. It is not strong enough to come to the heart, and it is violated by an engineer. But in the end, I plan to play this SBC-EC9100 board, the main reason is the processor equipped with the board (will I think before and after contradictory? Actually!) Because SBC-EC9100 Based on Freescale I.mx6ul processor, everyone knows that Freescale has been acquired by NXP, which is a contribution to the world from Motorola. The contribution to the world is still obvious, it is possible to disappear in the future. I feel unfortunately, there is a sense of hero (really a world of 艹 eggs, many great companies are all capital !!!), the spit is here, come and see this unnecessary and people Can't live "pity" board.
SBC-EC9100 hardware
The outer shape of the SBC-EC9100 is very like our previously touched, beaglebone black is very like, which should be said to be God, and the board is based on Freescale (now NXP) high-efficiency embedded processor I.MX6UL, Single-core ARM Cortex A7 processor, the main frequency is a bit low, only poor 528MHz, which is a bit phased compared to the mainstream single board computer on the market.
The peripheral resources of the SBC-EC9100 are not a lot, except for some major USBs, Ethernet, LCD, Camera interface, other peripheral functions need to be extended through the 80pin double-pin pin interface, more for engineers. DIY yourself.
From the actual card card, the SBC-EC9100 did not equip the WiFi / BT module. After reading, this thing is an option, it seems that the author's hand is a simple version of the "乞丐 version" ".
SBC-EC9100 onboard resources are as follows:
Freescale I.MX6UL G3, ARM Cortex A7 processor, 528MHz
Onboard 512 MB DDR3, 4GB EMMC
24 bit LCD interface
Support 10bit Camera interface
1 * 100M network port, 1 * USB OTG, 1 * USB Host, Micro SD Card, 1 * Industrial WiFi (optional)
Outer expansion interface 80pin (40 * 2), where the seat A is compatible with the Raspberry Pi 40 PIN extension interface
Provide expandable 1 * UART, 1 * 485, 2 * CAN, 1 * SPI, 1 * I2S, 1 * RMII, ADC, PWM
I.MX6UL application processor
In addition to the "乞丐 version" card, the onboard application processor is also the lowest end version in the i.mx6 family, so it is not difficult to find the market in the middle of the SBC-EC9100 board. End, using a single nuclear low frequency I.MX6UL processor, the entire board has no more than a multi-user experience, no more than human-computer interaction, compares to medical instruments, video surveillance, communication and other industrial embedded control areas .
The specific model of the application processor is MCIMX6G3CVM05AA, 14 x 14 mm BGA package, and integrated comparison has energy efficiency single-core processor ARM Cortex-A7, the maximum frequency is 528MHz, and there is also a variety of interfaces, including LPDDR2, DDR3, DDR3L, NAND Flash, Nor Flash, EMMC, Quad SPI storage, etc., there is also a wide range of peripheral interfaces, such as WLAN, Bluetooth, GPS, Display, and Camera, specific references to the official specifications and hardware system block diagrams shown below. .
Some detail diagrams of the following four SBC-EC9100 boards.

Ethernet interface, USB HOST / OTG interface

Power-on measurement
Since the SBC-EC9100 board does not have an output of the HDMI interface, the serial port may be selected or view the system through the LCD interface. The following picture is a 4.3-inch screen (with resistive touch screen) extension through the LCD interface, although the board is "乞丐 version" type, but wants to expand, things are a lot at all, and the English also provides a lot of external expansion. The module is not that price is not so cheap, it is better to go to a Bao Tao's benefit.
The board is supported by 5V power supply. After power-on, the factory built-in Debian system is running. The Freescale logo of the launch screen makes people tears, I don't know how long I can see.
User name, password is the default root.
Check the information of the CPU, a single core processor, and the frequency is 198MHz ~ 528MHz.
Because the wireless module on the board is not picked up, only the network cable can be inserted online.
SBC-EC9100 palette is a static IP, and the gateway is 192.168.2.1, which requires the configuration file in ETC / Network / Interfaces based on its own actual network condition. The most convenient way is to set it directly to automatically obtain the IP address, and you can connect it normally after setting OK.
On the functional test of the board, the English also provides the corresponding test manual, commonly tested with RTC, EEPROM, EMMC, GPIO, UART, RS485, USB, CAN, etc., this is not described here. The following figure is a touch screen test of the above 4.3-inch screen.
Said wearing a calibration similar to a resistive screen.
Video playback test, install MPlayer play video, and also verify the USB functionality by reading external storage.
Small video, or video that is not high for decoding requirements can be played normally, but the picture has a paste, and a slight high-definition video is directly "downtime".
Although the performance of the SBC-EC9100 cannot be compared with the currently mainstream board computers, the test tool is installed, and the test contrast board has a Raspberry Piece 2/3. , Banana dispatch 3, HIKEY.
Since I.MX6ul equipped with SBC-EC9100 only has a single core, only single core performance is only tested during the actual test.

Test results summary
As can be seen from the test results, I.MX6UL on the SBC-EC9100 board compared to the mainstream board computers, and finally found a single nuclear performance. Almost partner.
summary
Simply played the SBC-EC9100 development board launched by the English, how to say it, relying on Freescale I.mx6ul this processor, board peripherals expandable resources are still very flexible, but the board itself has no characteristic As the electronic enthusiast, it is really not found to be tossible, but it is necessary to know that the launch of the SBC-EC9100 board is not for this part of the population, more is the current industrial control or embedded field, to graphics Interface, human-machine interaction requires no high application area, if you do not ask for a requirement, there is also a way, and the B & D has a high-performance board SBC-EC8800 based on Ti AM437X processor. Interested you can go Official website Journal of Intermittent Network to see.
Although the performance of the SBC-EC9100 board is only comparable to the Raspberry Pivot 2 flag, but from the perspective of product development, I. MX6UL far is much better than the stable SOC on the Raspberry 2, one is Source, one is the supply cycle, which are essential factors in product mass production.
Therefore, the first topic of returning to the article should be that the NXP acquired Freescale, I.MX6UL will be "hero's end"? Answer: "Of course, for the graphical interface, the human-machine interaction requires not high entry-level industrial control or embedded field, I.MX6UL is still long."
