Description

The MYD-AM335X Development Board designed by MYIR is a high-performance ARM Evaluation Module (EVM) using the MYC-AM335X CPU module as the core controller board. It is based on 800MHz Texas Instruments (TI) Sitara AM335x family of ARM Cortex-A8 Microprocessors (MPUs) that deliver high DMIPs at a low cost while also delivering optional 3D graphics acceleration and key peripherals. These TI Cortex-A8 MPUs include industrial interface options, such as EtherCAT and PROFIBUS, and can support the Linux, Android and Windows CE high-level operating systems. The combination of graphics and connectivity support makes TI AM335x MPUs ideal for home automation, industrial automation, enterprise/educational tablets, portable navigation devices and networking. The board can work in harsh environment supporting -40 to +85 Celsius extended temperature operation for industrial embedded applications.


MYD-AM335X Development Board


The TI AM335x consists of 6 pin-pin compatible devices (AM3352, AM3354, AM3356, AM3357, AM3358 and AM3359) with various options including speed grades, packages, graphics and peripherals. MYIR is using the 15x15 mm, 0.8-mm ball pitch, ZCZ package AM335x ARM CPU on the MYC-AM335X CPU Module which is an SOM (System on Module) and has the core components AM335x processor, 512MB DDR3 SDRAM, 512MB Nand Flash and Gigabit Ethernet PHY chip on board and can be served as the core of your embedded system. It has two 2.0mm pitch 60-pin male expansion connectors, one 2.0mm pitch 26-pin interface and one 2.0mm pitch 10-pin interface to allow extension of all the controller signals and ports to the base board through headers and connectors, thus exposing more features of the AM335x Cortex-A8 Processors.


MYC-AM335X CPU Module


The MYD-AM335X base board has extended many features and peripherals with the support of the MYC-AM335X SOM and some extended controller chips including two serial ports, four USB Host ports, one USB OTG port, dual Gigabit Ethernet ports, one CAN, one RS485, one Micro SD, HDMI, LCD, Touch screen and more others.


User can integrate a different MYC-AM335X SOM on the same base board, thus making six variants of AM335x evaluation boards.

Question:
Does the MYD-AM335X have OpenGL ES2.0 implemented into the Windows CE7 kernel?

Answer:
Yes, we have implemented OpenGL ES2.0 into the Windows CE7 kernel for the MYD-AM335X development board.

2. What are the differences for the AM3352, 3354, 3356, 3357, 3358 and 3359 boards?

Question:
What are the differences for the AM3352, 3354, 3356, 3357, 3358 and 3359 boards?

Answer:

MYIR is using the 15x15 mm, 0.8-mm ball pitch, ZCZ package AM335x ARM CPU on the MYC-AM335X CPU Module and the main differences of the MYD-AM335X boards are from the CPU (AM3352, AM3354, AM3356, AM3357, AM3358 and AM3359) features including speed grades, packages, graphics and peripherals. Please refer to the file below:

 AM335x_Devices 


3. How to use extended UART on the MYD-AM335X board?

Question:
Hello, I want to know how to use the extended UART on the MYD-AM335X board and how do you define the UART numbers as for tty0~63, ttyO1~5 and ttyS0~5?

Answer:

Please refer to the MYD-AM335X user manual Figure 2-11 and Figure 2-12 as captured below:


Figure 2-11


Figure 2-12

Combine the MYC-AM335X user manual about the pin allocations, you will know how to use the extended UART.


About the UART numbers, please refer to below:

 ttyO1 --- UART1 
 ttyO2 --- UART2 
 ...... 
 ttyO5 --- UART5







4. How to use six serial ports of the MYD-AM335X board?

Question:
The MYD-AM335X board has six serial ports. How can I use all the serial ports?

Answer:

The MYD-AM335X board has six serial ports. But UART4 and UART5 have been reused with other functions. If sometimes you need to use all the six serial ports, we can modify the kernel.

  • The UART4 is reused with CAN, we use CAN by default

  • The UART5 is reused with K2/K3 button, we use K2/K3 button by default.

Note: So if you want to use UART4 and UART5, you can not use the CAN and K2/K3 button then.


Please make modifications about kernel as below:

1. Open the kernel file

$vi arch/arm/mach-omap2/board-am335xevm.c


2. Add UART4 and UART5 function definition codes if not exist.

/* Module pin mux for uart3 */
static struct pinmux_config uart3_pin_mux[] = {
        {"spi0_cs1.uart3_rxd", OMAP_MUX_MODE1 | AM33XX_PIN_INPUT_PULLUP},
        {"ecap0_in_pwm0_out.uart3_txd", OMAP_MUX_MODE1 | AM33XX_PULL_ENBL},
        {NULL, 0},
};

/* Module pin mux for uart4 */
static struct pinmux_config uart4_pin_mux[] = {
        {"uart0_ctsn.uart4_rxd", OMAP_MUX_MODE1 | AM33XX_PIN_INPUT_PULLUP},
        {"uart0_rtsn.uart4_txd", OMAP_MUX_MODE1 | AM33XX_PULL_ENBL},
        {NULL, 0},
};

/* Module pin mux for uart5 */
static struct pinmux_config uart5_pin_mux[] = {
        {"mii1_col.uart5_rxd", OMAP_MUX_MODE3 | AM33XX_PIN_INPUT_PULLUP},
        {"rmii1_refclk.uart5_txd", OMAP_MUX_MODE3 | AM33XX_PULL_ENBL},
        {NULL, 0},


3. Add UART initialization code if not exist, as below in blue words.

static void uart3_init(int evm_id, int profile)
{
        printk("--------uart3_init\n");

        /* Configure Uart3*/
        setup_pin_mux(uart3_pin_mux);
        return;
}

static void uart4_init(int evm_id, int profile)
{
        printk("--------uart4_init\n");

        /* Configure Uart4*/
        setup_pin_mux(uart4_pin_mux);
        return;
}

static void uart5_init(int evm_id, int profile)
{
        printk("--------uart5_init\n");

        /* Configure Uart4*/
        setup_pin_mux(uart5_pin_mux);
        return;
}

4. Add registration for the UART4 and UART5 and comment out the CAN and keys functions as in below red codes.

 {uart1_init,    DEV_ON_BASEBOARD, PROFILE_ALL},
        {uart2_init,    DEV_ON_BASEBOARD, PROFILE_ALL},
        {uart3_init,    DEV_ON_BASEBOARD, PROFILE_ALL},
        {uart4_init,    DEV_ON_BASEBOARD, PROFILE_ALL},
        {uart5_init,    DEV_ON_BASEBOARD, PROFILE_ALL},
//      {d_can_init,    DEV_ON_BASEBOARD, PROFILE_ALL},
//      {gpio_keys_init,  DEV_ON_BASEBOARD, PROFILE_ALL},
        {gpio_led_init,  DEV_ON_BASEBOARD, PROFILE_ALL},
        {NULL, 0, 0},


5. Re-compile the kernel and update the system.
