could you provide a precompiled file

i'm having problems installing the dependencies to compile an iso.

`reset` command will not delete command log before reset

The reproduction method is in this gif：

request: port this to Agon Light please

New image loads in emulation, hangs on real hardware

I compiled the OS + ROMdisk, producing os_with_romdisk.img, which loads and runs flawlessly in the emulator. However, after flashing the board with the same image, the computer hangs while booting the new OS.

The image is available here. It's configured to boot and run zorth.bin.

This is the dialog in the bootloader section (57.600, 8 bit, 1 stop bit, no parity):

That is as after as it goes.

How to add a program to the filesystem?

I use "load nnn" to load a program via UART and run it. No problem.

How do I do to have that program stored permanently in the file system, like init.bin?

It's a user program, not a bootable one.

Wiki for target `Agon Light`

I want to try it in the emulator, but I can't find any tutorials. The only useful information is a tweet from the target author, and I wish we had a wiki explaining how to use it

`less` command will clear the screen after exit it

less command on linux will not clear the screen, there's a little difference in this behavior.

how can i add new board to it

i have a diy z80 sbc

cpu:hd64r180rop
ram: 62256x2
rom:w27c512
clock:9.13mhz

can i use your boot loader ?

Can I read from STDIN byte by byte?

This code read from stdin and return a Forth counted string (len in the first byte). Tested using the emulator, while waiting for my board from Aliexpress.

; Parameters:
;   H   - Device to read from.
;   DE  - Buffer to store the line.
;   B   - Size of the buffer passed.
; Returns:
;   A   - ERR_SUCCESS on success, error value else

read_line:
    push h          ; device

    push de       ; buffer
    ld c, 0          ; line len
    ld (de), c      ; store line len.
    inc  de         ; Reserve 1 byte for the len.

    ;   Test for zero length buffer
    ld  a, 0
    cp  b
    jp  z, end

cycle:
    ; Read bytes by polling, one at time
    push bc
    ld  bc, 1    
    READ   
    pop bc 
    
    cp a, ERR_SUCCESS
    jr nz, cycle
br:
    ;   Move char to buffer
    ld  a, (de) ; a <- last char read
    inc de      ; buffer++
    ;   Update count
    inc c       ; used++
     
    ;   Check the ending '\n'   
    cp a, '\n'  
    jr z, end

    ; Check buffer full
    djnz cycle

end:
    pop de
    pop h

    ld a, ERR_SUCCESS
    ld (de), c      ; len of the counted string
    ret
