Error: Could Not Calibrate SDARM

F.y

Hi,

I am trying to run a but project on Arria 10 but I received a different error in Commands and also in Terminal.

I built a Arria 10 Soc boot from QSPI based on https://rocketboards.org/ and based on this page I tried to debug with Arm DS-5 but during a my .ds file running I received  :

"+restore u-boot-socfpga/spl/u-boot-spl-dtb.bin binary 0xFFE00000

and also in Terminal the other error is printed :

DDRCAL: Failed
WDT: Started with servicing (10s timeout)"

I already read most of answers in forums but most of them is for the last version of Quartus which is generate a preloader with BSP editor but in my case I built all with script. 

Is there any solution in this case?

    Hello, to echo my colleague Stephen's comments, you need to investigate why the boot loader has failed to initialize the memory at 0x01000000

    Reading through the log above, I see uboot being loaded to (the on-chip RAM at) 0xffe00000 - it is this code that would perform the necessary remapping (see for example fig 173 in this manual), but it reports that it 'Could not calibrate SDRAM'.

    If you cannot decipher the reason, I recommend you post to rocketboards or Intel forums, where you will likely get a more appropriate audience for your question.
