quartus_hps error: send_access_data() error while accessing DP Register - quartus_hps error: send_access_data() error while accessing DP Register Hello, I 'm working on the Cyclone V SoC, t his may cause by loading a wrong preloader. I have try quartus_hps with argument --boot=18, but it not useful. And there is only one way to boot device from QSPI. Anyone have some suggestion to solve this? There may be some one with same problem but no answer since 2016.

I will close this threa for now. Thanks. Regards, Aik Eu Replies: Re: quartus_hps error: send_access_data() error while accessing DP Register Hello Aik Eu, Its a customer board and use additional circuit. Regards BuddyZhang Replies: Re: quartus_hps error: send_access_data() error while accessing DP Register Hi BuddyZhang , Thanks for the info. Hmm... anyway I do not understand that specific kind of handling to this problem. Is the dev kit you are using a custom board or a development kit? Plus when manually reset the flash. You just need to perform the reset using the reset button on the board or using an additional added circuit to it? Thanks. Regards, Aik Eu Replies: Re: quartus_hps error: send_access_data() error while accessing DP Register Aik Eu, I am sure it not cause by hardwar issue. And finally there is a solution, reset flash while hps boot up then enable and write it https://forum.rocketboards.org/t/qspi-flash-programming/971 Replies: Re: quartus_hps error: send_access_data() error while accessing DP Register BuddyZhang , As I understand that command will not give errors as shown as I never have this issue before regardless of the board has or not been programmed with any relevant or unrelevant content. Would like to know the physical configuration on the board has been set correctly(referring to building bootloader for Cyclone V to boot from QSPI): Set BSEL jumpers to boot from 3.3V QSPI device: BSEL2=1 (left) BSEL1=1 (left) BSEL0=1 (left) Can work with the prebuilt images and perform the qspi flashing steps for the board instead of building the required files. Try to use later version of quartus programming tools if there is any problem. Another suggestions is to try with the GUI instead of running the command in terminal. Link for building bootloader for Cyclone V to boot from QSPI: https://www.rocketboards.org/foswiki/Documentation/BuildingBootloaderCycloneVAndArria10#Cyclone_V_SoC_45_Boot_from_QSPI Link for using pre-built GSRD: https://releases.rocketboards.org/2022.11/gsrd/c5_gsrd/ Can feedback to me if there is any problem when runnning the qpsi flash commands from the Cyclone V qpsi boot document. Thanks.

From your command it looks like you are trying to perform erase on the QSPI flash. Try to run "qaurtus_hps -c 1 -b 18 -o s" to perform cold reset and read the silicon id of the qspi flash. Would like to know if there is any issue with running this command. Thanks. Regards, Aik Eu
