Procedure :
1 electrical hardware devices ADFU let into the state , connect the USB to the PC side . If you have already installed the ADFU drive the properties shown below , if the display device or other property can not be identified , reinstall ADFU drive correctly.
2 Double-click on the main folder ATM7029_hardware_tools.exe, open the test interface is as follows :
Test item selection area
Green indicates normal ADFU devices connected
Red means no device is connected to normal ADFU
Button to start the test
Check the items needed to test , the test is as follows :
(1) PMU_initial: The main control on the PMU chip configuration items , configuration master , DDR and SD card required power . If this does not pass , please focus on examination of the PMU 24M clock and SPI interface is OK. The option is mandatory .
(2) DDR_32bit_scan: scan 32bit bit wide DDR data and address lines of the interface. The right to return to full A, an error is returned full 5 0-3 last bit indicates byte0-3 returns an error , return 4 shows the address error, return 5 represents initialization failed. Below shows , which means that the DDR byte1 error.
(3) NAND_CE1 / 2 / / 3/0: NAND flash interface to scan items. According to the actual hardware configuration, select the corresponding CE items. CE is usually double check CE1, CE2, four CE , then the whole hook. Right will return all A, and flash the ID information.
(4) SD_card: The T card is used to detect connectivity interfaces , make sure T card is inserted properly .
(5) Audio: The test is the master data lost through an audio interface to PMU chip, while the output sine wave audio signal through headphones and speaker, can be used to detect abnormal audio path.
(6) HDMI: The test will output an image to the TV , make sure the HDMI cable connected properly .
4 Click the Start button to start the test .
