Arty-a7-100t: Error for running bitstream

[L0stMyN4me]

We followed the steps of readme completely, firstly we execute the command (make CONFIG=rocket64b2 BOARD=arty-a7-100t vivado-gui )to generate the system arty a7-100t. tcl file, and then executing the tcl file in Vivado(2020.2) to generate the bd. The first time we did not modify the bd, we directly generated bitstream. Error reported: Insufficient LUT resources. Subsequently, we deleted some IPs, such as ethernet, and then generated bitstream, but the result was still an error report indicating insufficient resources. The development board we use is Arty-a7-100t,vivado version is 2020.2 Could you please tell me which step we did may have problems？

2-core system is too large for this board - insufficient LUT resources. Use single core configuration: CONFIG=rocket64b1

excuse me, according to your suggestion, we successfully created the project, but still cannot start Linux.It has the following error

We refer to this comment but it still dosen't work.

this is the pmod sdcard we used there is no sdio_cd pin, so we annotated it out from riscv_wrapper, and assign it a value of 1 PS: the same problem occurs when the sdio_cd pin is not modified Is it because of the pmod issue? Do we need to modify anything else?

The project is setup for Digilent Pmod SD adapter. Your adapter has different pinout. You need to modify board/arty-a7-100t/sdc.xdc to match your adapter. Also, make sure you use right socket on the Arty board - socket JB.
