My sabresd based new custom board, kernel report error:
mc_pfuze 1-0008: recv failed!:-5,0
mc_pfuze: probe of 1-0008 failed with error -5
Hardware reset to PMIC, boot loader can probe PMIC properly:
Found PFUZE100! deviceid=10,revid=11
Because our linux system software reset is WDOG based, it won't reset PMIC.
After reset ,boot loader will not report PFUZE100 found. Strange issue, Why?
With oscilloscope support, I found the PFUZE100 i2c access failed with no ACK in 9th i2c clk.
Anyone ever encounter issue like this?
