Unlock procedure for EFM32LG995F256

Psihuki

Hello!

Chip is locked.

I try to erase full chip  and load hex flash into EFM32LG995F256 using:

Windows10, Ulink2, MDK Arm 4.7.4, MDK Arm 5.28a in SWD mode

And i have errors:

In MDK 4.7.4:

invalid ROM table 

Cannot access memory

Flash Erase failed - Target DLL has been cancelled

In MDK 5.28a:

Unsupported access port

Flash Erase failed - Target DLL has been cancelled

Please help, how resolve it.. Setting, methods, software..

I found this procedure for unlock EFM32LG chips. But how to do it in Keil MDK Arm?

Thanks for any help!

    Thanks for your answer. I order jlink v9 ARM tool for unlocking, erasing and loading bin & hex file into EFM32, because software jlink can do it in 1 click.

    Silicon labs GUI = simplicity studio, don't support Ulink2, but support Jlink v9 Arm tool..
