Seems like configs for SigmaStar SSC377, SSC377D, SSC377DE are using wrong architecture:
BR2_cortex_a35=y
That is armv8 arch but if you check for example cat /proc/cpuinfo on SSC377D board it's says:
processor : 0
model name : ARMv7 Processor rev 0 (v7l)
BogoMIPS : 8.98
Features : half thumb fastmult vfp edsp neon vfpv3 tls vfpv4 idiva idivt vfpd32 lpae evtstrm crc32
CPU implementer : 0x41
CPU architecture: 7
CPU variant : 0x1
CPU part : 0xd04
CPU revision : 0
Hardware : SStar Soc (Flattened Device Tree)
Revision : 0000
Serial : 0000000000000000
And also in document https://linux-chenxing.org/infinity6/SSC337D_brief_datasheet.pdf SoC specified as Cortex A7 Core, not A35
So I think option for this targets should be
BR2_cortex_a7=y
