Part Number: AM5728
Hello,
We are facing booting problem in our custom AM5728 board,
specification of the board : 2 numbers of DDR (ddrmt41k256m16tw-107 xit:p) are interfaced to EMIF1 of AM5728 (EMIF2 is Not connected)
we tried booting from the possible methods like UART, m-SATA & via CCS (JTAG).
Following are the details of the booting methods:
1) UART - initially when set to UART boot mode we observed "VA! VA! VA! VA!" prints on UART3. Post loading of u-boot-spl.bin via serial-boot.pl (perl), we are able to Download u-boot-spl.bin but we are not getting "CCCCCC" or any other prints.
2) m-SATA - we have compiled the images according to custom board and We have kept the bootable images (u-boot.img, HLO, dtb) images & file-system in partition of m-SATA in respective directory.
3) CCS(JTAG)- Able to load spl bin file and spl symbol but we are not getting any prints on UART.
The following steps are followed:
a) uboot-spl.bin is loaded at 0x40300000 address via load -> memory
b) uboot-spl is loaded via RUN-> symbol load.
c) PC is set to 0x40300000
d) CPSR-> T is set to 0.
e) Debug is run, then no prints are observed in UART3, also there is error and CCS request for vector.s file. and PC is set to 0x0000000C.
The following files are shared for feedback as one zip file:
1) EXCEL of DDR configuration after populating with our custom board values.
2) DDR Configuration gel files modified as per EXCEL output and used for CCS booting method.
3) UART files and methods
4) mSata boot partition files.
