I am trying to export the script file from the EVM and write it back to the EVM. I get a write error and failed write.
I am using USB to GPIO 2 and Fusion digital 7.9.1. see snapshot below
Hello Murali,
Some of the registers in the device constantly update such as the RTC. If you try to import a file that was exported with validate write commands, the constantly updating registers will not read back the same value that was written, causing the error. When exporting, deselect validate write commands.
Best,
Walter
Hello Murali,
Before exporting, try clicking "refresh all" first to update the GUI and make sure all faults are cleared. This fixed the issue of stopping at address 0x10 for me.

The issue is some where else. The only register which is updated is the RTC. The Excel sheet shows the address 10h as 00, but gui sees it as 10
Hello Murali,
There are a few steps to disable PEC which should allow simple read and write without triggering the fault.
In the GUI, select the I2C tool in the tool menu.
In the tool, make sure the device address is set to 3C. In the write data section, to address 29 write C06B as shown and click send.
This should allow you to import without getting hung up on the error. Keep in mind that this must be done every time the device is power cycled. The device will revert to its factory programming with PEC enabled every time it is powered down. Let me know if this works.
Best,
Walter
