I get an error whenever trying to program an altera cyclone FPGA. I am trying to use the command line tool quartus_pgm in order to do this. I am currently on pop!_OS 20.04 linux (Ubuntu based) system, using 13.0sp1 quartus and trying to program the FPGA via an USB-Blaster.



The result can be seen in the screenshot in attached files.


I checked the options of quartus_pgm and did not find where to change the device part number. I do not have much experience using quartus.



I did find a way to list devices connected to the cable using:

Owners or operators of establishments that are involved in the production and distribution of medical devices intended for use in the U.S. are required to register annually with the FDA. This process is known as establishment registration (Title 21 CFR Part 807).


Congress has authorized the FDA to collect an annual establishment registration fee for device establishments. A detailed list of the types of device establishments that are required to register and pay the fee can be found at "Who Must Register, List and Pay the Fee." There are no waivers or reductions for small establishments, businesses, or groups.


Generally, establishments that are required to register with the FDA are also required to list the devices that are made there and the activities that are performed on those devices. If a device requires a premarket submission before being marketed in the U.S., then the owner/operator should also provide the FDA premarket submission number (510(k), De Novo, PMA, PDP, HDE).


Registration and listing provide the FDA with the location of medical device establishments and the devices manufactured at those establishments. Knowing where devices are made increases the nation's ability to prepare for and respond to public health emergencies.


Obviously the Altium part is 'pin labelled' different than the Orcad footprint. The Altium netlist should be editable (e.g. text file), so look up U11 in the file and see what they label the pins as (maybe like 1A. 1B, 2A, 2B?). Then map the U11 footprint accordingly.


As far as I can see, the names are identical. I even have the original schematic library source. They are all the same. The PCB footprint is somewhat different. Altium named the 4 pins 1, 2, 3, and 2. It is a SOT223 where there are 3 pins on one side and a large tab on the other. The middle pin (2) is internally connected to the large tab (2). When OrCAD translated them, it changed the name to 2_1. As a result, I renamed pin 2_1 to 4 and even added a fourth pin to the schematic symbol and it still indicates that they are not matching.


I fixed this "extra" pin and made sure the schematic symbol had the same number and #24 will go away but #3 will stay. Is there a detailed way to fix this? How am I to know how many pins are in the schematic and PCB symbol?


Hi CadAce2K, I did not fully understand what you meant. I was finally able to understand that even though I made the schematic symbol have 4 pins, I did not label the number correctly for it to match the current footprint that was made. I mistook pin number mismatch to be amount and not a label of sorts. I understand now that device pin number mismatch means that the number label of the symbols and footprints have to match and not meaning the amount of pins.


The major number identifies the driver associated with the device.For example, /dev/null and/dev/zero are both managed by driver 1, whereasvirtual consoles and serial terminals are managed by driver 4;similarly, both vcs1 andvcsa1 devices are managed by driver 7. Thekernel uses the major number at open time todispatch execution to the appropriate driver.


Version 2.4 of the kernel, though, introduced a new (optional)feature, the device file system or devfs. If thisfile system is used, management of device files is simplified andquite different; on the other hand, the new filesystem brings severaluser-visible incompatibilities, and as we are writing it has not yetbeen chosen as a default feature by system distributors. The previousdescription and the following instructions about adding a new driverand special file assume that devfs is notpresent. The gap is filled later in this chapter, in Section 3.10.


When devfs is not being used, adding a new driverto the system means assigning a major number to it. The assignmentshould be made at driver (module) initialization by calling thefollowing function, defined in :


The command to create a device node on a filesystem ismknod; superuser privileges are requiredfor this operation. The command takes three arguments in addition tothe name of the file being created. For example, the command


creates a char device (c) whose major number is 254and whose minor number is 0. Minor numbers should be in the range 0 to255 because, for historical reasons, they are sometimes stored in asingle byte. There are sound reasons to extend the range of availableminor numbers, but for the time being, the eight-bit limit is still inforce.


Please note that once created by mknod, thespecial device file remains unless it is explicitly deleted, like anyinformation stored on disk. You may want to remove the device createdin this example by issuing rm /dev/scull0.


To load a driver using a dynamic major number, therefore, theinvocation of insmod can be replaced by asimple script that after calling insmodreads /proc/devices in order to create thespecial file(s).


The last few lines of the script may seem obscure: why change thegroup and mode of a device? The reason is that the script must be runby the superuser, so newly created special files are owned byroot. The permission bits default so that only root has write access,while anyone can get read access. Normally, a device node requires adifferent access policy, so in some way or another access rights mustbe changed. The default in our script is to give access to a group ofusers, but your needs may vary. Later, in Section 5.6 in Chapter 5, the code forsculluid will demonstrate how the driver canenforce its own kind of authorization for device access. Ascull_unload script is then available toclean up the /dev directory and remove themodule.


The arguments are the major number being released and the name of theassociated device. The kernel compares the name to the registered namefor that number, if any: if they differ, -EINVAL isreturned. The kernel also returns -EINVAL if themajor number is out of the allowed range.


Every time the kernel calls a device driver, it tells the driver whichdevice is being acted upon. The major and minor numbers are paired ina single data type that the driver uses to identify a particulardevice. The combined device number (the major and minor numbersconcatenated together) resides in the field i_rdevof the inode structure, which we introduce later.Some driver functions receive a pointer to struct inode as the first argument. So if you call the pointerinode (as most driver writers do), the function canextract the device number by looking atinode->i_rdev.


[15] Distributions vary widely on the location of init scripts; the mostcommon directories used are /etc/init.d,/etc/rc.d/init.d, and/sbin/init.d. In addition, if your script is tobe run at boot time, you will need to make a link to it from theappropriate run-level directory (i.e.,.../rc3.d).


As far as I know, openCV enumerates devices and uses the index of it as a camera index.But the way it enumerates can differ among backends.Anyway, if you can enumerate devices as OpenCV do, you can match the index of the device and its information depend on your code.


If you can differentiate the cameras by their serial number or device and vendor id, you can loop through all video devices before opening with opencv and search for the camera device you want to open.


A device account number is crucial to the functioning of Apple Pay. By replacing customer card details with this unique and unrelated number sequence, merchants can take streamlined and secure payments.


According to the latest data from Statista, over 507 million iPhone users have enabled Apple Pay worldwide, equating to 48% of the user base. Apple Pay has seen the highest penetration in the UK, Canada, and the US, with over 30% of users choosing Apple Pay for online payments in all three markets.


This widespread adoption makes device account numbers a vital component of the online economy and the security of online payments. As a merchant, you should understand how DANs work and why they benefit your business.
