Part Number: AM68A
Other Parts Discussed in Thread: SYSCONFIG

Hi TI

Could you please follow up the full schematic review for our new AM68A customer?

They did the initial review using Schematic CheckList Tool provided via ti.com.

Please contact me via my email since I can not upload the customer's design file here.

mailto : jack.cha@arrow.com

Thanks.

Regards, 

Jack

    If the customer completed the schematic review using the Spreadsheet Tool, what open issues/questions resulted from that effort? The purpose of the checklist is to help reduce design review times and to focus communication on specific areas of concern.

    Hi Robert

    They would like get TI feedback for their 1st PCB with AM68A.

    The opened issues are related with Boot Mode, Unused Pin, General Debug, General SysConfig Tool.

    Regarding Boot Mode - question in spreadsheet ask about 'eMMC Flash Boot mode'.  The processor support a primary boot device and a back-up boot device, which is only access if the primary boot device is not present/blank.  Some customers will have a flash memory (OSPI, eMMC, etc) as primary boot device.  If the primary memory is blank, then they will have a peripheral boot (UART, USB, etc) as back-up.  The peripheral boot can download a small flashing program used to update the blank primary memory.  SD Card can also be used as a mechanism to flash an on-board memory.

    The design includes JTAG connector (as recommended).  No issue found.

    For SD card interface - VDD_SD_DV connected to VSYS_IO_3V3 via resistor.  This means SD card will operate only at 3.3V.  This will be functional, but might operate at slower speeds compared to a dual-voltage UHS-I interface.  

    TI's system configuration tool provides mechanism to enter your specific hardware information into the tool and automatically generate some of the software configuration files/settings needed to operate your hardware.
