Hi,
I am having a very similar issue as seen in below thread.
e2e.ti.com/.../379997
I have a custom board based on the BeagleBoneBlack design. For the prototype boards, we have used the
exact same soc and DDR parts as the BBB.
On this board, trying to fine tune the DDR timing as explained in the wiki (processors.wiki.ti.com/.../Sitara_Linux_Training:_Tuning_the_DDR3_Timings_on_BeagleBoneBlack), we are getting 0x0 values for minimum, maximum, optimum and range columns..
We did try to invert the CLK_OUT from 0x1 to 0x0 in the gel file without changing any other values as an experiment suggested in the above thread, but still get the same results.
I have attached the following files
1. The CCS console error message (console_log.txt) []
2. The gel file we are using (BeagleBlack_400Mhz_4GbDDR.gel)
3. The xls file used to calculate parameters from board layout (RatioSeed_AM335x_boards.xls)
4. DDR3 board layout trace lengths (NETLEN_DDR3.txt)
By the way, we are using CCS v6.0.1.00040 and XDS100v2 JTAG.
With the register values from the BBB uboot, we were able to boot up UBoot.
But the Linux kernel does _not_ boot up. It fails randomly at different areas of the bootup sequence.
So I guess we really do need to find the fine tuned values to continue.
Thanks,
Warm Regards,
Harith
