LS1046 ardb flash program error on JTAG

[sreeragag]

Hi
We are trying to flash Hard coded RCW in LS1046ardb using JATG.
When we do flash operations on QSPI unprotect, blank check work, but cannot erase or program a file.
Also user reference of ls1046ardb says when we use Hard coded RCW, DDR controller and Core should not enabled. How can we program or set-up core and DDR controller disable?
Switch setting used
SW3[1:8]             SW4[1:8]          SW5[1:8]
0b01000110    0b10110011    0b01001111

Also we have tried with switch setting same SW3, SW4. and SW5 0b010011110

Hello Sreerag A G,

Please refer to the first section in this document Use CodeWarrior for ARMv8 to Debug U-boot and Linux Kernel and Bring up Bare Boards to do flash programming. In the default CodeWarrior initialization file OCRAM is used in flash programming rather than DDR.

Have a great day,
TIC
