ETH_VDDIO on SabreSD i.MX6 Quad EVK

[vincentchou]

Dear support,

Based on the i.MX6 EVK schematic, ETH_VDDIO should be 1.8V or 2.5V.  Unfortunately we accidentally wired 3.3V to ETH_VDDIO to NVCC_RGMII on our board.  Luckily we don't use any Ethernet components on our board.  I would like to ask your opinion whether this voltage will cause problem of the operation of the board and the CPU?

Hi Vincent

i.MX6Q max. NVCC_RGMII  is 2.625V according to Table 6. Operating Ranges

Table 6. Operating Ranges i.MX6DQ Datasheet, so 3.3V may cause problems to processor.
