[beagleboard] DDR3L DATA LINES ISSUE
Hi Sir, We have designed a PCB with AM5728 processor,and we have kept beagle bone X15 schema as reference. In Beagle board X15 schematics, in DDR3 section the data lines are not connected in straight forward way(i mean data line 15 of ddr3 is given to data line 10 of AM5728 and similarly in the same way for few other data lines.Please answer me the following questions 1)Please provide me the purpose for connecting the DDR3 in the above said way. 2)In beagle board X15 kingston make DDR3(D2516EC4BXGGB) is used and we have used micron chip(MT41K256M16HA-125 :IT) . The schema for DDR3 is same as beagle board X15. 3)Do we need to change any configurations for using micron chip in the kernel 4)Do we need to change the value of termination resistors used Please answer the above questions as we have presently struck in uboot level and there is problem in starting with the kernal Thanks, Chandan -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.

[beagleboard] PMIC test driver
Hi Sir, I am currently working on AM5728 processor with TPS659037 PMIC, It will be helpful if get links for the test drivers written for PMIC using I2C interface so that i can verify my board.

[beagleboard] REGEN1 pin
Hi Sir, I am designing a PCB using AM5728 processor with TPS659037 PMIC ,i have kept Beagle board X15 schematics as reference . I have a doubt on REGEN1 pin. The datasheet of TPS659037 says the REGEN1 output is active high but it has been pulled up to 3.3V in the load switch (TPS22965DSG)side .Also the default output configuration(OTP) for REGEN1 output is push-pull. So please suggest me how to design VDD_ON_3V3 line such that the TPS22965DSG should be ON so that i can configure PMIC for the required settings soon after i assemble the board.
