egzumer / uvtools Goto Github PK

I'm analyze source code and found some strange inconsistency.

Your uvtool utility uses write flash packet with data length fields 0x01,0x00, see this line:

// the length is fixed to 0x100 bytes
    const length_msb = 0x01;
    const length_lsb = 0x00;

    return new Uint8Array([0x19, 0x5, 0xc, 0x1, <...>, length_msb, length_lsb, 0x0, 0x0, ...data]); 

But k5prog flasher uses this packet with length in reversed order 0x00,0x01, see this line: https://github.com/sq5bpf/k5prog/blob/241ab18b61f6d8933fecf60643fe94322fbf4198/k5prog.c#L698

len=UVK5_FLASH_BLOCKSIZE=0x100;

writeflash[12]=len&0xff;
writeflash[13]=(len>>8)&0xff;

Could you please help to understand what is going on here? And which version is correct?
Thanks
