added bigtreetech SKR-Pico #2988
Conversation
|
I'm a fan of the Bigtree SKR boards and have built an MPCNC and a custom delta 3D printer using older ones, so this is really cool. I imagine the PIO can be really handy for doing precise, low (~0) CPU overhead step control! Did you manually change the boards.txt or package file? The CI is showing a different ordering of entries vs. what the script generates. You'll want to rerun your For the "build all boards" failure you'll need to define the commented-out SPI and I2C(Wire) defines. You can give legal defaults (see the plain Pico) or use |

I just checked the schematic and it looks like this has only 2 MB (16Mbit) of flash, so the 16 here should be 2. OTW things like the filesystem and EEPROM will go very, very wrong...

If https://www.reddit.com/r/BIGTREETECH/comments/19f58r4/skr_pico_flash_size/ is right and the flash is a W25Q16JVUXIQ then the boot2_w25q16jvxq_4_padded_checksum might be an even better match for the Boot2 (faster too, 4 data lines instead of 2), instead of the currently set boot2_w25q080_2_padded_checksum.

Could you be mixing up the Espressif DIO/QIO and the Pico. I thought only QSPI (i.e. 4) lines were supported by XIP. The _2 or _4 in boot2.s refers to the sysclk divisor, so a /2 is faster than a /4...

Correct. Taking that back. Clock div by 2 is better than div by 4.

you are right -
W25Q16 - Density 16Mb
in the fast read i read 16MB

so what is the best fit?

What's the serial output result when uploading https://github.com/earlephilhower/arduino-pico/blob/master/libraries/LittleFS/examples/SpeedTest/SpeedTest.ino and using either
boot2_w25q080_2_padded_checksumboot2_w25q16jvxq_4_padded_checksumboot2_generic_03h_2_padded_checksumboot2_generic_03h_4_padded_checksum
Don't forget to give it some filesystem size like Tools -> Flash size -> "2MB (Sketch 1MB, FS: 1MB)".
i hope i have done all correctly..
please let me know how i can test my changes locally -
is it save to link the repo to the arduino hardware folder?
