Unique ID registers in Cyclone V
Hello everyone, I need to uniquely identify individual devices at runtime from the HPS (ARM Cortex-A9) side. Does the HPS side of the Cyclone V SoC have any built-in unique ID registers, such as: - A hardware serial number - A unique device ID - OTP (One-Time Programmable) fuses with unique identifiers - Any factory-programmed identification values What I've Tried: I've reviewed the Cyclone V documentation but haven't found clear information about unique ID registers accessible from the HPS side (unlike some other ARM SoCs that have dedicated UID registers). However I have seen Unique ID present in the FPGA side (https://www.intel.com/content/www/us/en/docs/programmable/683336/20-3/cores-user-guide.html), but this is not useful for my use case. Any guidance, documentation references, or code examples would be greatly appreciated! Thanks in advance!

Qsys: EMIF IP Core: usr_reset associated Clock
Hello, I am a bit confused by the Usage of the emif_usr_reset_n signal of the Intel EMIF IP Core. I have added a EMIF IP Core to our Platform Designer project. Based on the Documentation (4.1.1.14. emif_usr_reset_n for DDR3) I would assume the usr_reset output to have an associated clock (emif_usr_clk) with a synchronous deassertion: However in Platform Designer this reset appears without any associated clock and I get reset adapters when assigning it to reset inputs which require synchronous deassertion. I tried to explicitly set the emif_usr_reset_n output associated clock and synchronous edge, by applying this setting: But then I end up with the following Warning and I can also confirm, that the corresponding emif.ip file does not have the expected associated clock setting. So my question is: Is the documentation (4.1.1.14. emif_usr_reset_n for DDR3) correct and is the emif_usr_reset_n output really synchronous deasserted? Why does Platform Designer does not recognize the correct clock association for this signal? How do I configure the IP in a correct way to avoid any unnecessary or unexpected automatically inserted reset adapter? best regards Fabianmmc blocks written = error
Hi, By using Agilex-i series dev kit.I'm able to write a OS file from memory[0] region of ddr to mmc,but unable to write a file from memory[1] region of ddr to mmc. bdinfo log lmb_dump_all: memory.cnt = 0x2 / max = 0x10 memory[0] [0x0-0x7fffffff], 0x80000000 bytes flags: 0 ( 2GB ) memory[1] [0x280000000-0x3ffffffff], 0x180000000 bytes flags: 0 ( 6GB ) While tranfering a OS file from memory[1] region of ddr to mmc. Error pop up message as " mmc blocks written = error ". Thanks M Gokulraj
Cyclone 5 FPGA UART driver, and read/write functions.
I am using a Cyclone 5 MitySOM on the Critical link dev kit. I am trying to setup a custom UART (RX, TX) lines from the FPGA GPIOs, not going through any external chip other than and FTDI connected to a PC. I prefer to have this code in System Verilog. I have found some example of source for the RX and TX transactions, but nothing on how they get integrated into the FGPA system. Can you please provide me some detail, example code, etc. of how I can setup a custom UART (115200), that I can send Hello World to the PC and have it come out in a terminal window. Want to use this for log/debugging as well as a simple menu system to process incoming commands to perform actions real time. Thanks, Chris

Cyclone® V SoC Development Kit
Hi Everyone: I am looking for Cyclone V SoC Development Kit installation for board rev C. From link https://www.intel.com/content/www/us/en/products/details/fpga/development-kits/cyclone/v-sx.html# Only found information for board Rev E. "kit Installation" is version 22.1. After download, and unzip, there is factory_recovery directory, can the files under this directory be used for restoring the factory settings for board Rev C? If not, where I can download the "kit installer" for board Rev C? Thanks
How to use putty in Uart-to-USB communication?
I recently posted a question related to a project I've been working on. I wanted help to achieve Uart-to-USB communication to transmit counting data from my DE10-Nano to my computer. This is the post: https://community.intel.com/t5/FPGA-SoC-And-CPLD-Boards-And/How-to-obtain-the-counting-of-TTL-pulses-from-an-FPGA/m-p/1542536#M26340 ShengN helped me a lot, he even provide the modifications to the design and the C code to achieve this. However, he mentioned that I would need help from this forum with the usb putty part. I have no experience with Putty, and I'm completely new with FPGAs and hardware programming (this project was assigned to me). How can I make use of the design I got so I can transmit the counting of the FPGA to my PC.
