iMX6 BOOT_CFG pins hard short to Ground?

[kircpat]

Hello,

Can the iMX6 BOOT_CFG pins (that need to be Low OR the ones that says "Reserved" in the Fuse Table) connected straight to Ground (instead of pulling to gnd using resistors). This will save me pcb space by getting rid of components

Thanks

Hi Chirag

recommended to follow standard practice for connection techniques

on the PCB during system development, please check sect.3.3.3 i.MX Connection

Hi Igore, can you pls also answer this question that I’ve posted to the one you already replied? (see attached)

Hi Igor,

For clarification purpose, does SD4 port on iMX6 Quad also support emmc 4.41? The reference manual indicates only SD3 port supports 4.41 (see attached snapshot from ref manual).

What's mode does SD4 support? DDR, SDR?

Thanks
