Hi,
In the legacy kernel, when starting, the error appears: the chip id is 0x5d00 ic cant match axp, please check...
Please keep in mind that the BSP code contains a lot of nonsense, the PMIC setup seems to be particularly problematic, with dramatic error messages even when everything is fine. So is there any actual problem with your box? And I don't know what "chip id" here refers to, but it's surely not the AXP ID from I2C register 0x3, since that is only 8 bits wide. That number looks more like from the first part of the SID, which is also used in the DVFS code to discern certain dies or SoC revisions.
In any case, are you sure that your device actually has a PMIC? It is not unheard of for TV boxes to drop that chip (many H6 TV boxes did), as fine grained power management might not be too useful in a TV box.
Cheers, Andre
P.S. Please try to add some Allwinner specific lists (see the CC: here), or the #linux-sunxi IRC channel to get quicker responses.
well, in the axp.h code the id is defined as 0x40, I tried changing it to 0x5d00, but it does not accept the u-boot compilation error, does anyone know how to change it, it seems to be an error in the number of registers available in the .h
