J6 Entry DRA718 1004.nu100_20180419-core-TI.pdfcan't boot from SD card (QSPI and eMMC are both empty), there isn't any message on UART1 TX.My condition isa. Power up sequence as LP8733-Q1 and LP8732-Q1 User’s Guide to Power J6Entry Figure 2. b. booting loader (518202 J6 entry EVM board version) in SD card.c. choice SYSBOOT[5:0]= 0b100010 => SD boot.d. Use 19.2MHz crystal on J6 Entry and sysboot[9:8] = 0b11 (19.2MHz is 518392 J6 ENTRY LOW REF version ).e. reset signal (porz) is high.We try to change booting loader to 518392 J6 ENTRY LOW REF version(download from web), but it still without any message on UART. (Maybe the download 518392 loader isn't correct.)Could you advise me what to do?Thanks a lot.Ryan.

Hello, Somnath, Sorry, I didn't make it very clear. 518202 is Spectrum Digital EVM (DRA71x/DRA79x/TDA2Ex-17/AM570x CPU Board Kit) schematic document number. 518392 is TI J6 ENTRY LOW REF EVM board schematic document number. I downloaded software from omappedia.org/.../6AM.1.3_Release_Notes. Thanks a lot.
Hi Ryan,The reference software provided for 518392 board does not support SD card boot.Please follow the instructions in section 3.1.3 of the document for flashing the board using USB peripheral boot.http://www.ti.com/lit/ug/tidudn2/tidudn2.pdfRegards,Vishal
Yes, we rebuild U-boot and run on Spectrum Digital EVM ,
but it still can't run on our PCBA.
We don't do any modification on Spectrum Digital EVM board.
