NCONT ERROR in ACK for access 0 : ACK = 0x01 when trying to connect with Arm DS debugger through JTA

Hi Richard_P,

Are you running Arria 10 SoC - Debugging U-Boot from the link below?

https://www.rocketboards.org/foswiki/Documentation/BuildingBootloaderCycloneVAndArria10#Appendix_45_Debugging_U_45Boot_with_Arm_DS_Eclipse

I think can check if your board got problem booting into the Uboot user space with UART logs without any armds involvement first.

Below are the necessary files to be flashed(refer document) into qspi flash at different addresses:

~/intelFPGA_pro/23.2/nios2eds/nios2_command_shell.sh \

quartus_hps -c 1 -o pv -a 0x0000000 u-boot-splx4.sfp

~/intelFPGA_pro/23.2/nios2eds/nios2_command_shell.sh \

quartus_hps -c 1 -o pv -a 0x0100000 fit_uboot.itb

~/intelFPGA_pro/23.2/nios2eds/nios2_command_shell.sh \

quartus_hps -c 1 -o pv -a 0x0300000 fit_spl_fpga.itb

*u-boot-splx4.sfp (FSBL)

*fit_uboot.itb (To enter Uboot user space)

*fit_spl_fpga.itb (Required to allow HPS DDRAM to be brought up, and must do be done in SPL)

Thanks.

Regards,
