Hi, To change AXP80x into RSB mode, put 0x7c value to register 0x3e. The value defined RSB_DMCR_DEVICE_MODE_DATA in sxirsb.c works 0x7e to the register. It needs to be fixed.
At least my Allwinner H616 with AXP305 works good with fixed value. By the way, I have a question Does Allwinner-A64 with AXP803 boards works with 0x7e value? -- SASANO Takayoshi (JG1UAA) <u...@mx5.nisiq.net> Index: sxirsb.c =================================================================== RCS file: /cvs/src/sys/dev/fdt/sxirsb.c,v retrieving revision 1.4 diff -u -p -r1.4 sxirsb.c --- sxirsb.c 24 Oct 2021 17:52:27 -0000 1.4 +++ sxirsb.c 10 Jan 2022 10:33:55 -0000 @@ -45,7 +45,7 @@ #define RSB_DATA 0x001c #define RSB_DMCR 0x0028 #define RSB_DMCR_DEVICE_MODE_START (1U << 31) -#define RSB_DMCR_DEVICE_MODE_DATA 0x7e3e00 +#define RSB_DMCR_DEVICE_MODE_DATA 0x7c3e00 #define RSB_CMD 0x002c #define RSB_DAR 0x0030
