Other Parts Discussed in Thread: ADS54J20, ADS54J40
I got an ADS54J20EVM board and I'm trying to read its configuration registers using ADS54Jxx GUI low-level view. As a start, I'm trying to read the LMK4828 ID registers (0x3-0x6, 0xC, 0xE) but only get zeros.
Using a scope I verified that SPI CLK and SDO signals are alive (measured on R69/R70). I also noticed that the GUI board selection pull-down menu only offers ADS54J40 and ADS54J20.
Any ideas what am I missing?
Thanks in advance,
