Hi,
I am using J-Flash SPI to program an external flash in my target system.
Programming is done as direct programming, via j-Link Pro (version 4.3) through SPI and keeping the target MCU reset by nRESET.
When J-Flash disconnect from the SPI, nRESET is released and my MCU starts executing.
So far everything is working like a charm, but when my MCU try to communicate to the flash it fails.
I have measured on the signals, and it shows a conflict on MOSI signal.
It appears that j-Flash does not tri-state "DI" (MOSI) when disconnecting from the SPI.
Is this a bug or as intended by j-Flash?
If it is intended, would it be possible eg. to manipulate the port setting via Exit Step?
Thanks and regards
Kaj
