Title: stm32-H405 and "Cannot get debug register" error
Post by: veritek on August 23, 2017, 10:28:21 PM
I am trying to set up Crossworks through an ARM-USB-TINY-H to program the STM32-H405 board.  Have the FTDI drivers loaded and now getting an error that says "Cannot get debug register".

Any ideas what I am missing?

In the options in Rowley try to lower the JTAG speed and increase the "JTAG Clock Divider" from 1 to 2 or 4.
