After developing a device on Omega2+, I created custom board for Omega2S+. Beside Omega2S+, the board has SD card, W25N01GVZEIG (NAND where CS1 is used for Chip Select), and FM24CL64B-G (F-RAM chip connected over I2C. In prototype phase, I didn't have W25N01GVZEIG so I never connected it to Omega2+ but designed the connection on the custom board.
The problem I am experiencing with Omega2S+ is constant rebooting after showing
[ 32.937566] 1. Phy Mode = 14
on UART0 while Omega2+ shows that three times. (find enclosed putty session captured on UART0 of Omega2S+. I had to rename it to .bin while I was unable to upload it but is plain text file)0_1572563211273_onionlog.bin
Also, I was able to activate console and input df -h that shows:
no /dev/mtdblock6 mounted to /overlay
and overlayfs:/tmp/root mounted to / with size of 61.0M
What might be wrong? The added NAND flash or is something wrong with internal flash that might be possible to fix with fresh image flashing from bootloader?
Many thanks for your help.
