Re: [ipxe-devel] [ipxe/pipxe] Raspberry Pi 4? (#2)

[IntelMiner via ipxe-devel]

Hi team,

I finally had some time to sit down and poke at this again.

I went ahead and wiped my old git copy and resynced from scratch just to make 
sure there weren't any lingering issues with testing. 

I upgraded to GCC 11.1.0 in the meantime, however I still seem to be getting 
the infiniband errors I mentioned previously @stappersg as well as another 
error, though the build continues after this first error in the "encode" library

Running a standard `make -j16` shows this error, but continues

```
enc/encode.c:1435:20: error: argument 5 of type 'const uint8_t *' {aka 'const 
unsigned char *'} declared as a pointer [-Werror=vla-parameter]
 1435 | const uint8_t* input_buffer, size_t* encoded_size,
  | ~~~^~~~
In file included from enc/encode.c:9:
./include/brotli/encode.h:293:19: note: previously declared as a variable 
length array 'const uint8_t[*encoded_size]' {aka 'const unsigned 
char[*encoded_size]'}
  293 | const uint8_t input_buffer[BROTLI_ARRAY_PARAM(input_size)],
  | ~~^~~~
enc/encode.c:1436:14: error: argument 7 of type 'uint8_t *' {aka 'unsigned char 
*'} declared as a pointer [-Werror=vla-parameter]
 1436 | uint8_t* encoded_buffer) {
  | ~^~
In file included from enc/encode.c:9:
./include/brotli/encode.h:295:13: note: previously declared as a variable 
length array 'uint8_t[input_size]' {aka 'unsigned char[input_size]'}
  295 | uint8_t encoded_buffer[BROTLI_ARRAY_PARAM(*encoded_size)]);
  | ^

```

After that it will switch to the bin-arm64-efi ipxe build, before eventually 
erroring out with

```
drivers/infiniband/flexboot_nodnic.c: In function 'flexboot_nodnic_create_qp':
drivers/infiniband/flexboot_nodnic.c:368:53: error: implicit conversion from

[Kevin Hellemun via ipxe-devel]

Im on macos and cant seem to build this for rpi4. I tried using a vargant box 
based on ubuntu but no luck there neither. Any pointers on how i could get this 
build for rpi4?

@PeterSurda Update!

It took some finesseing to get it to work on my build box (Gentoo needed the 
`iasl` package for those relevant files)

I ran into an ipxe build error with some junk relating to "infiniband" 
(possibly an issue with using GCC 10.2?) but commenting that out fixed it

Embedding my boot script seemed to work as well. It pulls down a kernel + 
initrd and (attempts) to boot them

However it now hangs at

`EFI stub: Booting Linux Kernel...`
`EFI stub: Generating empty DTB`
`EFI stub: generating boot services and installing virtual address map...`

But I know that's (probably) outside the scope of iPXE and likely a kernel 
configuration issue on my side

Thank you very much for all your help however :) Hopefully this thread helps 
others in future too

Re: [ipxe-devel] [ipxe/pipxe] Raspberry Pi 4? (#2)

[Peter Šurda]

So it looks like netboot.xyz does internally use pipxe, and researching did 
help me find out how to build pipxe for RPi4. Here is a condensed version:

1. manually update all submodules, in `edk2`, `edk2-platforms`, `edk2-non-osi` 
and do `git pull origin master`
2. edit the Makefile, replace `RPi3` with `RPi4`
3. also in the Makefile, disable git submodule update as it will then revert 
the update (just comment the line `git submodule update --init --recursive`)
4. also in the Makefile, change `IPXE_TGT` to `bin-arm64-efi/snp.efi`
4. run `make`

The resulting EFI file seems to work OK on my RPi4.

@IntelMiner I'm in the same situation as you. I think this project doesn't 
support Raspberry Pi 4. However, https://github.com/netbootxyz/netboot.xyz 
does. I'm now trying to find out how to build it with your own menu.

Re: [ipxe-devel] [ipxe/pipxe] Raspberry Pi 4? (#2)

[IntelMiner]

Additional: While I was writing the above comment. My Pi 4 booted, gave a "net0 
no such network device" error. Looped through the "Start PXE over IPv4" and 
then IPv6 

And then actually found net0 and attempted to boot!

Could this perhaps be a bug in either iPXE or the UEFI firmware I'm using?

Re: [ipxe-devel] [ipxe/pipxe] Raspberry Pi 4? (#2)

[IntelMiner]

Apologies for the necro-post. But this was one of the first results in Google 

I've been tearing my hair out for several hours now trying to get a scripted 
iPXE to boot on my Raspberry Pi 4. I've tried using both the iPXE upstream, as 
well as the version 1.20.1 build that @rgl's repository provides 

No matter what version I build, executing a `make bin-arm64-efi/ipxe.efi 
EMBED=myscript.ipxe` or even building without the script builds a binary that 
boots, but then does not show any ethernet devices :(

I've got the latest EFI 1.24 firmware running, and have also tried 1.16 and 
1.17 due to at least one thread noting that it may have errors netbooting 

I've found a few pre-made iPXE binaries that do already work, but I want to 
embed a script in to mine for HTTP booting

Is `make bin-arm64-efi/ipxe.efi` still the correct build command for the 
Raspberry Pi 4? Or am I missing some step somewhere

Forgot to update this issue... but I have to report that upstream ipxe (1.20.1) 
works fine with rpi4-uefi (you need v1.15 for rpi4+8gb support).

FYI, I have a vagrant environment for building ipxe and uefi at 
https://github.com/rgl/raspberrypi-uefi-edk2-vagrant.

Hi folks.

https://rpi4-uefi.dev/ tracks the Pi 4 UEFI. GENET driver is developed and 
currently being cleaned up and soon to be upstreamed - and the expectation is 
that it should work with iPXE.

Feel free to join us on the #rpi4-uefi-dev channel on the Arm 
Developer-Ecosystem Discord server (https://discordapp.com/invite/fqRhc8y)

There was a bunch of discussion last week on the IRC channel regarding pipxe on 
raspberry pi, I believe with the pipxe maintainer (or one of them).
Sorry I did not follow which pi version they were discussing.

[Rui Lopes]

I mean, does the `pipxe` project has plans for having iPXE running in the 
raspberry pi 4 firmware?

Currently, it seems there's beta support for PXE booting at 
https://github.com/Hexxeh/rpi-firmware, but how about iPXE? Are the two 
projects related? Working together?

Sorry, I didn't notice/look-for there was even a IRC channel / mailing list! 
Will ask there.
