Hi,
I am trying to update/first flashing NVM of XL710-BM2 chip which is on our custom board and there is an Ubuntu 20.04 on a aarch64/arm64 architecture. It is said in the following link that the initial NVM configuration must be performed externally using SPI.
https://community.intel.com/t5/Embedded-Intel-Core-Processors/XL710-on-ARM64-architecture/m-p/237049
However it is stated in section 3.4.1.2 of the datasheet that "A blank Flash programming mode is provided (besides the normal programming mode previously mentioned in item 2.) where the Flash can be programmed directly without the EMP being involved via one of the legacy methods:
a. Memory mapped write via host memory BAR....."
1. Is there any tool/executable that can perform memory mapped write via host memory BAR to flash a blank NVM?
2. If there is not, can we use SMBUS connections for the initial programming of NVM? XL710-SMBUS is connected to our on-board MCU, if it is possible we would prefer to use it.
3. We can program NVM externally using SPI interface by using jumpers. During this initial programing, does XL710 drive SPI pins or does it left them open-drain or unconnected? If it does not, we also need to unconnect the SPI lines between NVM and XL710.
4. There are binary files in the Non-Volatile Memory (NVM) Update Utility for Intel® Ethernet Adapters 700 Series—Linux* file. I want to use configuration 7.2 but there are five possible binary files as listed below.
XL710_X710_9p30_SFI_MCTP_CFGID7p2_Dual.bin
XL710_X710_9p30_SFI_Backplane_MCTP_CFGID7p2_Quad.bin
XL710_X710_9p30_SFI_Backplane_MCTP_CFGID7p2_Dual.bin
XL710_9p30_SFI_NCSI_CFGID7p2_Quad.bin
XL710_9p30_SFI_MCTP_CFGID7p2_Quad.bin
It is a bit confusing to understand which one is the correct. There will be SFP+ modules connected to the 4 ports of XL710 and also we don't have NCSI. Hence is the file XL710_X710_9p30_SFI_Backplane_MCTP_CFGID7p2_Quad.bin proper for our board?
5. We will directly write this binary file to the address 0x00 of the NVM, is it?
6. At the end of the process, we will also need ARM64 version of nvmupdate64e executable , ice driver and i40e driver in order to be able to update firmware over PCIe with ARM64 architecture. How can I access source files of nvmupdate64e?

Previosly I have checked that file.
my architecture is arm64. nvmupdate64e tool, ice driver and i40e driver, All of these are written/compiled according to x86_64 architecture. I couldn't succeeded to use the tool.( I have tried qemu etc..) Hence I need source files of nvmupdate64e tool in order to compile it for arm64 architecture.
Also the binary files that I mentioned in my 4th question are obtained from the link that given in that file. However there are 5 different configuration 7.2 binary files. It is a bit confusing.
Actually in the case that I gave it's link, you said that it is impossible to write to xl710 with nvmupdate64e. Is it true, even it's NVM blank?

Hello @CarlosAM_INTEL ,
I reviewed the section 3.4.5.4 of the datasheet and also reviewed the entire chapter 3.4. Non-Volatile Memory.
The section 3.4.5.4 is about Reprogramming a non-authenticated module mapped outside shadow RAM. However I want to program a BLANK FLASH.
Can you answer the six questions that are listed in my first message, please?

Hello, @mdursun:
Thanks for your reply.
We need to address the following question to understand the situation:
What is the place of purchase of the Intel® Ethernet Controllers XL710-BM2 related to this situation?
We are waiting for your reply.
