the issue could be the wrong console= argument on the kernel command
line. In the current socfpga_config5.h I see
#define CONFIG_BOOTARGS "console=ttyS0" __stringify(CONFIG_BAUDRATE)
A comma is missing after "console=ttyS0"
It should be
#define CONFIG_BOOTARGS "console=ttyS0," __stringify(CONFIG_BAUDRATE)
Could you please test it? Thanks.
Best regards,
Anatolij
