ARM DS USB BLASTER or USB BLASTER II ? - ARM DS USB BLASTER or USB BLASTER II ? Good morning everyone. I have a custom board with the CycloneV SoC on board. This board has 2 JTAG connectors, one for the FPGA configuration and the other for the HPS section. I wanted to know if the Intel version ARM DS ide (Arm* Development Studio Version 2023.1 for Intel® SoC FPGA) also supports an external USB BLASTER for debugging, in addition to the external USB BLASTER II. regards, Luca. Replies: Re: ARM DS USB BLASTER or USB BLASTER II ? UPDATE 07/13/2024: After an endless series of tests I finally understood that the problem was simply the fact that I was trying to debug an application compiled to run on the DDR SDRAM, without having initialized the DDR via u-boot! Now I can debug ARM DS with both USB-Blaster-II and USB-BLASTER-I (both work)! Now I'm trying to understand if there is a driver for ETHERNET that I can use in BARE-METAL mode. Does Intel's HWLIB have this driver for CYCLONE V SoC? Regards, Luca. Replies: Re: ARM DS USB BLASTER or USB BLASTER II ? I wanted to inform you that I purchased the USB Blaster II, but unfortunately the problem has remained unchanged. I also wanted to ask if there is a step by step guide to be able to compile and debug bare-metal on the cyclonev soc with the arm ds software (not arm-ds5 which is declared obsolete!). I would like to be able to use the Boot-Rom - > Preloader -> BareMetal-App configuration Replies: Re: ARM DS USB BLASTER or USB BLASTER II ? Hi GOMEZ_IT, I’m glad that your question has been addressed, I now transition this thread to community support. This thread will be transitioned to community support. If you have a new question, feel free to open a new thread to get support from Intel experts. Otherwise, the community users will continue to help you on this thread. Thank you. Replies: Re: ARM DS USB BLASTER or USB BLASTER II ? OK thank you. Then I will try to buy a USB BLASTER II and try to use it. I will update the post once the test is done. Replies: Re: ARM DS USB BLASTER or USB BLASTER II ? Hi GOMEZ_IT, Unfortunately, we cannot provide clarification on that matter as Arm Development Studio IDE (23.1) is not our product. Therefore, we have limitations in offering credentials on this point. But in the Arm® Development Studio's Hardware and Host Platform Requirements, on page 18, it does mentioned the requirement to use the USB Blaster II. Regards, Fakhrul Replies: Re: ARM DS USB BLASTER or USB BLASTER II ? Thank you Fakhrul for your reply. Could you confirm that debugging with USB-BLASTER (ver 1) doesn't work, and gives the same errors I described in previous posts? Replies: Re: ARM DS USB BLASTER or USB BLASTER II ? Hi GOMEZ_IT, Sorry I might have missed your post. It's recommended to use USB Blaster II because it's faster and more reliable for debugging. Regards, Fakhrul Replies: Re: ARM DS USB BLASTER or USB BLASTER II ? I also tried connecting my SEGGER JLINK to the HPS jtag port of my board. By connecting, here is the result: Looks like the hps part is being detected correctly! Can anyone tell me if USB BLASTER 1 (NOT USB BLASTER II!!) can be used to debug the ARM DS IDE? Replies: Re: ARM DS USB BLASTER or USB BLASTER II ? It's really frustrating. I've been trying to debug the cyclone v soc for weeks. No way. My situation: With quartus attaching to the jtag FPGA I have no problem: With quartus, attaching to the jtag hps I detect this: With Arm Development Studio IDE (23.1) if I try to debug (with external usb blaster 1) on jtag hps I always get this error: PATH variables are ok, and the IDE correctly recognizes my usb blaster (version 1): The PATH variables are ok, and the IDE recognizes My custom card is practically the same as Terasic's DE10-nano (in fact the Linux image of the DE10-nano runs correctly and everything works, including the ethernet port). The only difference is that I have NOT soldered the QSPI flash onto the board. Could this be the problem? The MSEL[4:0] are 01010 The BOOTSEL[2:0] are 101 (boot from sd card) The CLOCKSEL[1:0] are 00
