09:56 <Jones42> regarding "read"ing a fitimage from a raw partition into memory: since there is no file system, is there a way to determine the size of the fitimage, i.e. how many blocks I should read?

09:57 <Jones42> Or do people just read the whole partition into memory to be safe?

14:21 <Tartarus> It's best to read the partition, yes

18:17 <clamor> Tartarus: hello! Do you mind if I organize sandbox adjustment along with of graph and video bridge into one pull request? Once sandbox changes are approved of course.

19:49 <Tartarus> clamor: That sounds good, thanks

19:50 <clamor> Tartarus: awesome. Thank you

19:51 <dormito> I'm working with the nxp_fspi driver, trying to get it to work with the i.mxrt1170. I noticed however that it has chipset specific info for the lx2160, so I looked at it's referance manual: The lx2160 has 1KiB FIFOs for both the IP RX, and IP TX fifos.. but the u-boot driver data has 512/1024 for the driver data. Anyone know if this is a mistake, or is there a reason it diverges from the RM?

20:13 <marex> dormito: maybe u-boot uses half of the fifo for RX and half for TX ?

20:13 <marex> git log -p on that driver does indicate nothing ?

20:34 <dormito> hmmm. looks like the driver was pulled from linux in that state... maybe the linux git logs have more info

20:39 <marex> apalos: is Jerome around here ?

20:39 <marex> dormito: yes

20:45 <dormito> Hmm... seems like its first upstream linux commit had it that way too. But looking at the i.mx8 RM, I think the lex2160 data was copied from it (during initial dev), and then never updated.

20:48 <marex> dormito: could it be that the 512 is there due to SPI being full duplex ?

20:48 <marex> i.e. 512 bytes go out, and at the same time, 512 bytes go in ?

20:48 <marex> half fifo for TX, half for simultaneous RX ?

20:51 <dormito> I'm still learning about the hw (mostly was thinking this would be a "wire up the device tree" thing), but I read the RM to be indicating there is both a RX fifo, and a TX fifo. Different RMs have thing as being different sizes: e.g. lx2160 has 1024 bytes for both, but one of the i.mx8 series has rx=512,tx=1024

20:51 <dormito> so I don't think it's a software division of the fifo size

20:57 <marex> dormito: ask the kernel driver author whether there is a bug then ?

21:01 <dormito> yeah probably a good idea... it was an @nxp.com email... so they better be able to figure it out. lol

21:02 <marex> :)

21:06 <apalos> marex: no i dont think he is
