urgent UCB9248 andUCD9222

Other Parts Discussed in Thread: UCD9222, UCD9248, UCD9240

Hi:

    Question 1:I use the power of the 6657EVM entry UCD9222, but is not able to connect a USB - TO - GPIO,Use the Texas Instruments Digital Power Manufacturing Tool Version 1.2.132;Advanced->Device Scaner tool ->DEVICE_ID&DEVICE_CODE...donot connect,show No devices found;As like as two peas I designed and 6657EVM entry;Please give me some advice; 

    Question 2:I use the power of the xilinx XC7K325T EVM (K7 EVM entry UCD9248,Connect the also don't show No devices found;The reference program download display :device validation failed  Device UCD9248 @address 52 was not found ;device validation failed  Device UCD9248 @address 53 was not found ;device validation failed  Device UCD9248 @address 54 was not found ;I donot know how  can't find what caused the address;

   Question 3:Use the Texas Instruments Digital Power Manufacturing Tool Version 1.2.132;use the TI “C6657_EVM_UCD9222_v03.xml” What needs to be software Settings; XILINX_EVM program software do I need to set;

  • Hi,

    It probably has one PMBus Host in the EVM, you need to check with it, because you could not has two host.
    Also, you need to check the jumper status, to make sure the PMBus pin are linked successfully.

    Thank you.
  • Hi:

        thank you; but I am using two pieces of software, there should be a host, I  check the jumper status is good; PBUS not feedback ACK;

    The design of the I have three 9628 and one 9222,I get rid of 9222 is same K7 EVM ,The same connection;How do I determine whether the chip work;

    the chip V33FB is4V  V33DIO is 3.3V  V33A is 3.3V,Set up addr-0, addr-1 ; I  check the jumper status is good. so I can also check something?

       Thank you 

     

  • Hi
    I found the reason of the problem;But some other problems;
    I change voltage of Fusion power Design Offline ,Export xxx.XML replace the before file;
    There are three files,and one Scripts->KC705_RevE_TI_Addr52_53_54_R0;The other three files input->KC705_RevE_UCD9248_U55_addr52_R0;KC705_RevE_UCD9248_U56_addr53_R0;KC705_RevE_UCD9248_U89_addr54_R0;
    1. Download by sixty percent;I have modified the KC705_RevE_UCD9248_U55_addr52_R0;KC705_RevE_UCD9248_U56_addr53_R0; voltage;
    Is my through software export file is wrong?Or I need to be modified KC705_RevE_TI_Addr52_53_54_R0?
    2.If I want to download a chip file alone, what should I do?KC705_RevE_UCD9248_U55_addr52_R0 donot download by Fusion power manufacturing tool;
    thank you
  • Hi,

    You could use the latest version of Fusion Digital Power Designer to modify the configuration, the link shows below.
    www.ti.com/.../fusion_digital_power_designer

    Besides, what you need to pay attention is there can be only one host on the PMBus. Otherwise data will be corrupted. Please disconnect the on-board host from PMBus, or keep it in reset when use the USB-to-GPIO adapter.

    Thank you.
  • hi
    thank you; I'm in the debug look;
  • hi :
    1. I downloaded a few the following error, I think, is to read voltage value is not enough,I checked all the places, don't know what is the reason why!Please give me some advice;

    14:57:14.218 CUSTOMER ERROR Summary READ_VOUT on rail #1 (0.003 V) was not within 3% of VOUT_COMMAND (1.000 V)
    14:57:14.239 CUSTOMER_LOGONLY ERROR Summary READ_VOUT on rail #1 (0.003 V) was not within 3% of VOUT_COMMAND (1.000 V) at TIDP.Factory.TaskLibrary.UCD9240.Validate_Vout_Device_Reading(Int32 rail_num, Double percent_pass) in c:\Anne_TI\Workspaces\FusionTools-Main\Libraries\TIDP\TIDP.Factory.TaskLibrary\UCD9240.cs:line 548 at TIDP.Factory.TaskLibrary.UCD9240.Validate_Vout_Device_All_Rails(Double percent_pass) in c:\Anne_TI\Workspaces\FusionTools-Main\Libraries\TIDP\TIDP.Factory.TaskLibrary\UCD9240.cs:line 596
    2. How to use the fusion_digital_power_designer;After I download export file also appear the above error;online ,offline ,
    connection PMbus,There is no change modify some parameters of the board!
    thank you
  • It appears from the posts that you are using a script that Xilinx created with the Fusion Manufacturing Tool for one of their evaluation boards.

    As I recall, the script would load the configuration for three UCD9248 devices and then it would run some basic tests to determine if the rails were functioning.

    The error you reported in the previous post comes from the script functions that check the rail operation, the script is expecting the 1.000V rail to be functioning within 3% as a quick check of functionality and the output appears to be off as it is reporting 0.003V.

    Can you provide a schematic of the power system and the configuration files which you are trying to load?

  • hi 

       I can give you on Monday.How do I add to the web site to you, or you give me a your E-mail, I add attachments to you on Monday

    thank you

  • hi
    I can also describe the use of I,the xilinx KC705 SchematicsEVM,UCD9248 Address 52 use 1.0 V to 1.0 V to 3.3 V to adj V,
    The design of the I didn't use adj V,I'm fusion_digital_power_designer closed 2.5 V and export XML file,Address 53 also changed a voltage, export XML file;The original EVM entry and modify the file error;

    14:57:14.218 CUSTOMER ERROR Summary READ_VOUT on rail #1 (0.003 V) was not within 3% of VOUT_COMMAND (1.000 V)
    14:57:14.239 CUSTOMER_LOGONLY ERROR Summary READ_VOUT on rail #1 (0.003 V) was not within 3% of VOUT_COMMAND (1.000 V) at TIDP.Factory.TaskLibrary.UCD9240.Validate_Vout_Device_Reading(Int32 rail_num, Double percent_pass) in c:\Anne_TI\Workspaces\FusionTools-Main\Libraries\TIDP\TIDP.Factory.TaskLibrary\UCD9240.cs:line 548 at TIDP.Factory.TaskLibrary.UCD9240.Validate_Vout_Device_All_Rails(Double percent_pass) in c:\Anne_TI\Workspaces\FusionTools-Main\Libraries\TIDP\TIDP.Factory.TaskLibrary\UCD9240.cs:line 596


    VOUT_COMMAND register Detection of deviation from normal output voltage fluctuations ,Do you have any good Suggestions?I check what hardware, or software to modify what place.
    2. The TI website tutorial is too simple, How to use the fusion_digital_power_designer;After I download export file also appear the above error;online ,offline ,connection PMbus.There is no change modify some parameters of the board!
    You know, the power supply does not work, the board was scrapped.
    thank you
