thank you guys, i updated the bootloader in the Nano, and it solved the problem.

Hi, Back after a while and trying to make use of a Raspberry pico.
Copied and pasted the file but when uploading it
fails :(
LittleFS.h: No such file or directory.

I should mention i tried to follow th einstructions but i don’t see an option for setting this -

Set Flash Size to the option that gives FS: 1MB . On the Raspberry Pi Pico this is 2MB (Sketch: 1MB, FS: 1MB).

This allocates enough space for use by LittleFS to save the entire workspace with save-image .

Using a Rpi4, Arduino 1.8.13

@gbar Have you followed the instructions here:

RP2040 boards - Installing uLisp

It sounds like you’re using the Arduino core, which doesn’t have LittleFS. You need to use the Raspberry Pi RP2040 Boards core.

hi, succes! thought i’d done it but clearly wrong.
Next problem is unplug and plug. try to upload the blink sample -
2 | (defun blink (&optional x)
| ~ ^~~~~~
| )

exit status 1

Compilation error: expected ‘)’ before ‘blink’

johnsondavies · 2023-04-06 19:29:16 UTC

Can you give more details about what you’re doing? That error message isn’t a uLisp error.

gbar · 2023-04-07 19:01:33 UTC

Sure. I’ve uploaded the most recent ulisp, all good -
scanning for RP2040 devices
Flashing H: (RPI-RP2)
Wrote 336896 bytes to H:/NEW.UF2

unplug and plug it back in again (i’ve already uploaded so don’t need to do again right?)
i select new sketch and copy the blink LED sketch in and it doesn’t like that

johnsondavies · 2023-04-07 21:08:22 UTC

I don’t think you’re actually talking to uLisp when you get that error. Do you get the uLisp prompt; for example:

22911 >

gbar · 2023-04-09 17:38:28 UTC

my problem was entering the blink program.
I’ve got he latest Arduino IDE and selecting serial monitori smaybe different?
It all looks a bit weird and not how i expected, my fault. Got the LED blinkingbut it’s not like the program is accesible this way, it seems anyway to me. I’ll look elsewhere on the forum for how to write,edit and upload code.
Thanks muchly

If you get stuck again just ask on this forum; there’s lots of help available!

Whats the best method for working on a program?
Do you write it in a text editor and try to run with SBCL or something?
Whats the workflow?

gbar · 2023-05-04 09:28:25 UTC

in the Serial Monitor? no. Uploads ok with a Low Memory available, stability problemsw may occur.

Open the Serial Monitor, as per
http://www.ulisp.com/show?19XT
no ulisp prompt

johnsondavies · 2023-05-04 09:56:58 UTC

Try typing something like aaa followed by return.

Does anything appear?

gbar · 2023-05-04 10:35:24 UTC

nope

Am I correct in thinking that you’re using a Raspberry Pi Pico Board, and the Raspberry Pi RP2040 Boards core with the Arduino IDE?

I’ve just tried uploading the latest release 4.4c of ARM uLisp to a Raspberry Pi Pico board. I’m running on a Mac, using Arduino IDE 1.8.19. I left all the Board settings at their defaults, apart from:

Flash Size: 2MB (Sketch: 1MB, FS: 1MB).

I get:

Sketch uses 150460 bytes (14%) of program storage space. Maximum is 1044480 bytes.
Global variables use 194116 bytes (74%) of dynamic memory, leaving 68028 bytes for local variables. Maximum is 262144 bytes.

I’m not sure why your upload is using so much more memory. Have you selected any custom settings on the Board menu options?

In any case, you can ignore the error “Low memory available, stability problems may occur” that you get - it’s just a warning.

After uploading uLisp I can just select the Serial Monitor window, and then enter Lisp statements in the input box at the top of the window. I’m not sure why you’re not getting this.

Are you on Mac, Windows, or Linux?

Morning,

Pi4 Raspbian.
Genuine Pi Pico W
Ctrl-A copy paste into Geany (file size 238.1KiB) i think then saved to desktop. Copied again into arduino…
Copied straight into Arduino today and same.

plugged in previous PiPico (not W) and

Build options changed, rebuilding all

Now i get the the lisp prompt…fool
