Samba SM35-J-T20 does not start up after update

[Andrus]

Hi !

 

looks like something bad happened.

Updated SM35-J-T20  system using USB to COM adapter and Visilogic 9.8.9 

Had communication with SM35-J-T20 before, but display do not light up after powerdown.

How to enter bootstrap mode ?

 

Tried, that power off, wait 10 sconds, then pressed touchscreen and power back. No sucess.

 

Any guidelines ?

Hello,

 

Try as follow:

1. Turn off the PLC
2. Touch and hold the screen
3. Power on while screen is touched
4. Touch twice Update the BinLib, Boot and O/S (115200 baud rate, 1 sec timeout)
5. Download a blank project

 

If it didn't helped, contact support@unitronics.com with the results.

Hi !  I tried as R.Moses guided and succeed to install  BinLib and Boot

Then tried to install OS , but it got error on PC screen during update. 

 

Contacted Unitronic Tech support and from there got an extra tip:

Try as follow:

1. Turn off the PLC
2. Touch and hold the screen.
3. Power on while screen is touched.
4. You will see a countdown on the PLC screen.
5. Touch the HMI screen twice . The countdown should have stop.
6. On VisiLogic configure the communication settings with a baud rate of 115200 and a timeout of 1 sec
7. First  update only the BinLib
8. When BinLib has finished updating, please update only the Boot
9. When Boot has finished updating, update only the O/S.
10. Download a blank project

 

Tried many times to update O/S, but it stopped during install.

as last effort I just refrain using computer, went to have dinner and when came back, it was OK
