we have a custom CM4 carrier board.
a) CM4 with eMMC (Raspberry Pi OS)
In the custom board, have used HDMI0. So we've added
Code: Select all
framebuffer_priority = 2
in the config.txt file along with USB enable.
CM4 connects to a mobile phone hotspot but not able to ping.
We do not see anything on HDMI n neither access on console.
The I/P Voltage level on cm4 and output are fine on Both carrier Board
what more can be looked into?
Tested with IO Board and works fine.
b) CM4 without eMMC
with Raspberry Pi OS Lite
Act LED stays on
doesn't connect to a hotspot.
Works well in IO Board.
All the voltage level looks good SD_PWR is 3V3.
