Nor Flash Forum Discussions
I am currently trying to download flash (both sof and elf)file to EPCS (S25FL128SAGMFi011) on DE-1 SoC (Cyclone V 5CSEMA5F31C6).
By using the method in AN98558, I have succeeded downloading everything to my FPGA board and the command shell displays everything correctly. But it can only be proceeded once.
After the first time, I power off and on the FPGA board. Then I will get this error in Nios2 command shell: Error(209014): CONF_DONE pin failed to go high in device 2. Make sure all communication cables are securely connected, select a different device, check the power on the target system, or make sure all nCE pins are connected to GND.
I am a software engineer and I don't find any settings on Quartus that can set these pins. My questions are:
1.How can I reprogram the EPCS again via Nios2 command shell?
2. Do I need to use any external circuits or devices to actually set these pins to GND?
I am using Quartus 18.1 on windows 11 and the methods for Quartus 17 mentioned in AN98558 works perfect for me. I have attached the pictures of FPGA, S25FL128SAGMFi011 and the error message below.
Any suggestion will be appreciated. Thank you.Show Less
The S70GL02GS has two sector protection models.
Highest address protection model ,lowest address protection model
Could you please tell us each application .

what does last letter "A" stands for in this MPN? cannot find on the data sheet
I need a guru to help me here. We bought a bunch of Cypress flash memories S34ML04G204BHI01 and we also have some Cypress S34ML04G204BHI003 from the past. I couldn't find the S34ML04G204BHI003 online anymore, I am assuming it's end of life. My question is what the difference is between S34ML04G204BHI01 and S34ML04G204BHI003? Is there any firmware change required from S34ML04G204BHI003 to S34ML04G204BHI01 at all?Show Less
Can only write28 bytes in one write 24bit address quad command.
Looping can write a large size via the small chunks
The device appears to be locked in quad mode ?
Is there ANY jedec sequences that should work
Here a synopsys controller is sending commands erase/ get device id etc all work
Perhaps some "trick" bit must be set.
The mbed os code targeting cypress appears to simply dump data to the fifo.
Is there any "kit" from infineon to easy see the chip do ALL the tricks ?
Thanks for any reply !
At the timing shown in the data sheet of S29GL512T11DHIV10
Even if the data is read, it cannot be read (data output is open (L due to pulldown))
I'm searching for the cause while still in the state of
What are the possible conditions for unreadable factors?Show Less
Soft Error Rate discussion on NOR Flash S29GL512T in thread from 08/07/2019 07:55AM provided a value for SEL rate of the device. Is a formal SEU/SEL report file available on NOR Flash S29GL512T?
Can the s25fl128lagnfa010 be used with FPGAs, such as A7, K7, zynq7020 series FPGAs of Xilinx. Looking forward to your reply!Show Less
I’m trying to use the S25FS064SAGBHI020 as a drop in replacement for the ATXP032-CCUE-T, an old EOL'ed Adesto NOR Flash device.
Will anything bad happen if I have either VSS or VCC tied to one of the DNU pins on the device (for example Pins B1, C1, or D1)?
