Hi, all,
When i Activate uart2 via rsetup, many issues make ttyS2 unusable :
- a getty is still running /dev/ttyS2
- group should be dialout on /dev/ttyS2
If
- I stop getty on ttyS2 via systemctl,
- chown root:dialout /dev/rrtS2
- chmod g+rw /dev/ttyS2
- install un jumper between pin8 and pin 10
then minicom -D /dev/ttyS2 -b 9600 SHOULD show echo of my keystrokes…
Please note :
1° I found no problems activatiing uart4 via rsetup, jump pin 19&21, test minicom OK on /dev/ttyS4.
2° all forum articles reffering to this kind of issue suggest solutions incompatibles with rsetup
