你好，请问问题解决了吗？我也遇到了这个问题。我的wifi模块是bw121，飞易通的。也是sdc0作为sdio.

使用以下指令构建
mkfs.ubifs -x zlib -m 4096 -e 258048 -c 245 -F -r oem_res -o oem_ubifs.fex

@zzz555 The clock signal may be operating at a speed outside the bandwidth of your oscilloscope. Check the Hz setting of your clock, and ensure it is less than the bandwidth of the oscilloscope (likely 100 MHz).

If it is higher, then the signal will be attenuated. Configure the scope to be AC-coupled and try increasing the scope gain to see a faint signal.
