good day

now how do I change the jtag pinset of the pic16?

morning folks!

register 0x0F is the 'feature' register

Hm... is there a way to write to the pic i2c when the driver is loaded?

but I don't think the functionality was integrated in the driver

hm... okay

Bertl: when I `i2cset -y 4 0x40 0x0F 0xE` I read back (with `i2cget -y 3 0x40 0x0F`) 0x0F

not sure why you would write 0xE there, but yeah, you should read back what you write there

http://vserver.13thfloor.at/Stuff/AXIOM/BETA/PICJTAG/i2c_slave.c

bit 0, yes, so 0x0 vs 0x1

0x0 is the primary, and 0x1 is the secondary

yup

ok

also is there a way to query the firmware version?

no, unfortunately there is no firmware identifier via I2C

ah I see

MEETING TIME!

great!

then bluez

yup

The data from the host is received and a temporary ACK is sent via that, I will develop it further

I think that's it from my side

i'll report then

so i was finally able to write a live partial bitstream...at a targeted LUT (a frame)

faces many issue along the way... had to study the bitstream and xilinx nuances

wrote this script: https://github.com/Swaraj1998/xilinx-devcfg/blob/master/scripts/gen_partial_bitstream.py

now my next task is to be able to somehow 'mark' specific structures (like an LUT)... and find out where it is actually mapped (i.e. its frame address)

thats it from my side!

eppisai: do you have news for us as well?

last week,I discussed with BAndiT1983 on topcs like display driver, using centralDb to access variables,and other doubts

that those were not meant to their, so using centralDb now, and calling that in virtual display driver

thats it, from my side :)

I don't think so, I think onscreen keyboard, moving string framebuffer width to utils is done..

if not and everything is finished, please do

right

Thank you : )

There are a few expressions that I am not sure how to express, so I will consult with Mr. Rex as I proceed.

( I wanted to learn about  the PCBs of AXIOM beta this week but could not. I will following weeks.)

if you have any questions regarding the hardware, do not hesitate to contact me

just Bertl here :)

yes, that's what I meant

Shohei: would you also be interested in working on CAD related tasks?

great, I will think about what we can do together as first step

Thank you :) But it might take time since I am not familier at the first time since

Thank you :)

I did remap the mipi lanes to the Zynq (https://files.niemo.de/photo_2021-02-15_18-14-37.jpg).

Sadly the SI seems to be not to great and one lane is stuck (only outputs '0').

(as Bertl said).

yay!

oih :(

many thanks!

the ESD coating spray I wrote about last week did not seem to hold what it promised

so I shifted my focus entirely on getting the component trays for hardware assembly printed with the ESD philament

so I printed 4 trays so far and one was filled today with parts and label: https://paste.pics/e0b0cc0b6d796e3deb4b40f852e609c6

a good portion of the components is still in belgium but oscar promised to ship over what we got so far in the coming days

2 components are still in delivery limbo

on the bright side I received the jlc stencil for the HDMI plugin module today

on another front we received new micro sd cards (sandisk ultra) and bertl helped me put together a benchmarking process to fill the entire card with random data and read it back again afterwards to measure read/write speeds

results are OK with the roughly 5 cards I benchmarked so far

the first one always fails, maybe Bertl has an idea why that could happen

my last topic is the GSOC application that we need to finish ASAP

the general survey and forms will be no problem for me to complete but the idea page clean up and addition of new tasks requires a joint effort

this is the Plan B material in case the 3d printing of component trays fails for some reason

Bertl: any sata news to share with us?

unfortunately I didn't manage to get the software side set up before the meeting, so no news at the moment

ah, too bad, thanks!

no is the time

ok then, meeting concluded

thanks for moderating!

off for now ... bbl
