Hi all,

   

SCB Mode can control RS485 enable pin?

   

Or there are solutions to deal with the RS485 communication

   

In addition, I found that SBC pin can not configure the UDB UART

   

So it cannot be done through the UDB UART RS485 communication, unless changed to the other pin

   

My aim is to make RS485 accomplished through SCB Bootloader.

The SCB-UART seemingly is not able to perform an RS486-interface directly. Is there a reason you do not use the UDB-UART? After the bootloading process finished the UDB is free and may be used by your bootloadable program.

 May be difficult, because the first batch has been put into pilot production 100PCS ,careless in big trouble.

Or

   

File a technical case at Cypress: Top of this page "Support & Community ->Technical support->Create a MyCase". This will bring up a Cypress Engineer who REALLY knows the PSoC4 from its inside. Maybe there exists some rarely documented routing features through some register-writes to solve your problem.

 Has been coordinated with the customer,

   

The next stage then add these features

   

This can be redesigned PCB pin
