I ran a set of 20 DMA (Direct Memory Access) streaming programs using a bash script and it suddenly stops working. Trying to a single fpga_dma_st_test command again gives me this error -> ./fpga_dma_st_test: error while loading shared libraries: libopae-c.so.1: cannot open shared object file: No such file or directory If I try to reconfigure the FPGA using fpgaconf, I get the following error -> sysfs.c:1281:sysfs_write_u64() *ERROR* : Failed to write reconf.c:218:clear_port_errors() *ERROR* : Failed to clear port errors reconf.c:358:xfpga_fpgaReconfigureSlot() *ERROR* : Failed to clear port errors. What's the reason for this error? And is there any way to fix this? Thank You, Hrishikesh S.
