I want to issue an I2C-command before booting the kernel. Does the u-boot for ZYNQ supports I2C? I didn't found it activated in any ZYNQ board, so I am wondering why!? Any hints how to activate? My first experiments to enable it failed with a reboot: Zynq> i2c probe Valid chip addresses:Error, wrong i2c adapter 0 max 0 possible Error, wrong i2c adapter 0 max 0 possible undefined instruction pc : [<00000004>] lr : [<1ef3b2d8>] reloc pc : [<e50ca004>] lr : [<040052d8>] sp : 1db25d78 ip : 00000030 fp : 1ef3b16c r10: 00000002 r9 : 1db25ee8 r8 : 1ef8a617 r7 : 00000000 r6 : ffffffff r5 : 00000000 r4 : 00000000 r3 : 00000002 r2 : 0000080a r1 : 00000000 r0 : 1ef9ba30 Flags: nZCv IRQs off FIQs off Mode SVC_32 Resetting CPU ...
What is expected for the parameters for (I guess it is this command ?): i2c nm chip address[.0, .1, .2] - write to I2C device (constant address) -- _______________________________________________ meta-xilinx mailing list [email protected] https://lists.yoctoproject.org/listinfo/meta-xilinx
