Remote System Upgrade for ARRIA 10 FPGA Devices over UART with the Nios II Processor - Remote System Upgrade for ARRIA 10 FPGA Devices over UART with the Nios II Processor Hi @n_scott_pearson We want design Remote System Upgrade for ARRIA 10 FPGA Devices over UART with the Nios II Processor. 1. We want use UART terminal to upgrade .rpd file to flash EPCQL1024 can you explain me how to design that one. we tried all the example design but we are not able upgrade remotly. Replies: Re: Remote System Upgrade for ARRIA 10 FPGA Devices over UART with the Nios II Processor Hi @JohnT_Intel little endian of .rdp file Replies: Re: Remote System Upgrade for ARRIA 10 FPGA Devices over UART with the Nios II Processor Hi, May I know if you generate big endian or little endian format of rpd file? Have you try the other format? Have you verify the contain of the flash to be correct? Replies: Re: Remote System Upgrade for ARRIA 10 FPGA Devices over UART with the Nios II Processor Thanks @JohnT_Intel yes I powered off and turned on but there is no output. Replies: Re: Remote System Upgrade for ARRIA 10 FPGA Devices over UART with the Nios II Processor Hi, After you update the rpd file, do you performed reconfiguration or power cycle the board to see if the new image is being configured into the FPGA? The reason is that the rpd file update is only updating the flash content and not reconfigure the FPGA Replies: Re: Remote System Upgrade for ARRIA 10 FPGA Devices over UART with the Nios II Processor @BoonBengT_Altera @JohnT_Intel @Deshi_Intel @n_scott_pearson flash upgraded completely . 1. after upgrading it is not giving expected result, it means after upgrading led should glow. if load .sof of same project lead will glow.but if load .rpd file led is not glowing. upgrading is taking more than 3 hours(Uart baudrate value is 115200) Replies: Re: Remote System Upgrade for ARRIA 10 FPGA Devices over UART with the Nios II Processor Hi @BoonBengT_Altera Thanks for reply.... This is our requirement: Remote System Upgrade over UART based on Nios II Processor with EPCQ1024 (ARRIA 10 FPGA Development Kit 1. I reffered example project of max 10 and cyclone V remote system upgrade over uart based on the nios || Processor. 2. there is no warning 3.yes * In nios eclipse we don't how to write main.c program * generating the .rpd file using .sof and .hex we not abled update over flash below i attached one capture in that enter programming file displaying if i tried to update .rpd file it is not sending Replies: Re: Remote System Upgrade for ARRIA 10 FPGA Devices over UART with the Nios II Processor Hi @APPU_appu , Thank you for posting in Intel community forum and hope this message find you well. Please help us better understand the situation with a few clarification, 1) What are the design example that have been tried? 2) As mention not able to upgrade, is there any error/warning upon compilation or programming? 3) Upgrades are done via .rpd files, did you managed to try programming via active serial interface? Warm regards. BB
