Greetings,
We have a custom board based on the LS1046A that needs to boot from QSPI NOR flash. We are having a problem with the RCW that we put into the QSPI flash. Something goes wrong at power on and the board is not booting.
In order to debug this, there is a Reset Request Preboot Loader Status Register (RSTR QPBLSR) that we would like to use CodeWarrior TAP to connect to the target and read out while in this state. There is a ERR_CODE bitfield in this register that will hopefully give us some breadcrumbs on where to look next, but I'm having trouble figuring out how to read it with TAP. I don't want an initialization script to reset anything on the target. Just connect and read this status register. How can I accomplish this using CodeWarrior TAP? I.e. read CFG_CCSR_RSTRQPBLSR[ERR_CODE]. I believe for the LS1046A this would be base address 1EE_0084 for error register
