  6. 6. Detailed Description Page 6 Processor module AX-SOM-CL335x based on TI AM335x 2 Description of Functional Blocks 2.1 Processor AM335x As the basic processor, the family of TI AM335x in the case of SPBGA-N324 with suffix ZCZ is used. To clock the processor we use 24 MHz (main) and 32.768 kHz (for the work of inner RTC processor TI AM335x) crystals. It is possible to install processor with the frequency range from 300 MHz to 1 GHz. 2.2 Memory DDR3 By default, the configuration uses memory DDR3 Samsung K4B4G1646B-HCK0 of 256 Мbite (It is possible to enlarge it to 512 Мbite). The beginning of the physical address of DDR3 is 0x8000 0000. 2.3 Memory NAND Flash By default, the configuration uses NAND memory Samsung K9F2G08U0CSCB0T00 of 256 Мbite (It is possible to enlarge it to 1 024 Мbite). The memory is attached to bus GPMC with the width of 8 bit. 2.4 Power Supply Controller PMIC As power supply controller PMIC, we use TI TPS65217C. Controller PMIC attached to bus I2C0 and its address is 0x24. 2.5 Boot Sequence for Texas Instruments AM335x By default, the following sequence is specified: 10011 - NAND->NANDI2C->MMC0- >UART0 2.6 Graphic System The processor supports the use of a display with the resolution to 2048х2048 (to 24 bit per pixel). The matrix has slot X9 (AXK5F60547YG) to attach LCD module TD035STEE (the resolution of 480х640, a resistive touch screen, backlight). It is possible to attach other displays supported by processor AM335x. 2.7 Audio System The audio system is based on codec TLV320AIC3007 of Texas Instruments. It is controlled via I2C interface, the address is 0х18. To transfer audio data we use interface MCASP0 of processor AM335x. The mono audio input is attached to microphone MK1. The mono audio output is attached to slot X6 FH02W for a speaker of 8 Ohm 0.5 W. The stereo output is attached to slot X5, SJ1-42514 Stereo Jack 2.5 mm. The stereo input and output are attached to GSM/GPRS module, which makes it possible to make a standard cell phone. The linear stereo input is attached to extension slot X16.

  13. 13. Detailed Description Page 13 Processor module AX-SOM-CL335x based on TI AM335x 4 Module Firmware Module Firmware per UART0 1. Make sure that the terminal program (examples of minicom in OS Linux and Tera Term in Windows are taken only) after the power is switched on shows symbols “CCCCCC”. If this does not happen, the prime load mode for UART0 shall be set. 2. Switch off the module power. 3. For minicom it is important to specify the buffers size (1K) to transfer via XMODEM/YMODEM: Ctrl-a o, File transfer protocols, and write commands sx -vv -k and sb - vv -k. 4. Transfer via Xmodem the start loader: Ctrl-a, s, xmodem select file u-bootspl.bin (select by pressing space bar twice and go to catalogs) and press enter. For Tera Term select File->Transfer->XMODEM->Send… and indicate file u-boot-spl.bin. 5. Switch on the power and wait to see the current percentage of the loading (for Linux PC only). 6. After ROM is successfully loaded, the code initiates the start loader that waits to transfer u-Boot loader via Y modem protocol. 7. After the second “CCCC”, send via Y modem: Ctrl-a, s, ymodem select file uboot.img and press enter. For Tera Term select File->Transfer->YMODEM->Send… and indicate file u- boot.img. 8. If everything is successfully loaded you can see the invitation of U-Boot#
