Created attachment 1561 [details] linuxrc script from initramfs I'm running this on microblaze CPU on a Xilinx Virtex-4 FPGA. I have tested this on 1.16.0, 1.16.1 and 1.15.3, all with the same results. I followed several examples of the initramfs bootscript that should be used to call switch_root, and I think I have them okay, except that I'm always coming across the same error. 'No such file or directory'. My SD card with a root filesystem is mounted at /mnt. I have tried the following as the last argument to switch_root. * init * linuxrc * /linuxrc * /init * sbin/init * /sbin/init * /mnt/sbin/init Nothing works. I have attached by initramfs linuxrc script. Also, this appears if I use 'ash', or 'hush' as my default shell. Bootlog from my initramfs /linuxrc is as follows. --START-- Switch root script...

Found the problem. My buildroot was not copying ld.so.1 into the output/target/lib directory.
