FS26 in debug mode to read FS_STATE register has been 0x14, in the manual does not change the return value description, according to the flowchart in the manual, after power-on should go through the OTP program will enter 01001 Init FS, then you can write the initialization register data stream, but at present due to FS_STATE problems, I can not go to init FS. In the community I found such a help, but unfortunately there is no specific description and solution, the link is as follows:
Fs26 failed to initialize using the function Sbc_fs26_initDevice()
Hello,
Is your power-up sequence successfully completed and the RSTB pin released? If not, please see below the RSTB Low reason checklist.
If necessary, please check regulators output when RSTB low with oscilloscope, please also check if there is OV/UV flag reported.
BRs, Tomas
