Tested all A4xxA410, the oldest shows trouble
It does differ from what we have on file. I loooked it up I dumped the FW of this very camera in 2014. That dump went into the general FW collection, what is there is identical in timestamp and file content to the dump I saved in my own FW dumps file structure. So you seem to be right. How does one restore this? Bit by bit?
private sub Initialize() adr = 0xFFE439D3 SystemEventInit() buf = AllocateMemory(16) Poke8(buf, 0x25) byte = Peek8(adr) if byte = 0x2d then dangerous_eventproc(adr, buf, 1) end if FreeMemory(buf)end sub
]There is only one bit of obvious difference, at offset 0x2439d3.The following Canon Basic script should restore the original byte
How neat, even with a fail-safe check. Did it and guess what it works again. Wow... So that does happen... Only if powered off and on the shelf too long or even when used more frequently one wonders... Re-Dump enclosed. Thanks! I got a new camera
Tested it, looks as it did before to me.
!newfi2={ Filename="TEST.DAT", ObjectFormat=0xbf01, ObjectCompressedSize=52} return con:ptp_send_object_info(newfi2)!return con:ptp_send_object(('x'):rep(newfi2.ObjectCompressedSize))ls -l TEST.DAT
Can you run the following to check if standard PTP operations are affected? Code: [Select]!newfi2={ Filename="TEST.DAT", ObjectFormat=0xbf01, ObjectCompressedSize=52} return con:ptp_send_object_info(newfi2)!return con:ptp_send_object(('x'):rep(newfi2.ObjectCompressedSize))ls -l TEST.DAT

What is this where do I use it? With the "ls -l TEST.DAT" I thought it to be for a bash like shell - but no...
At the chdkptp prompt, after connecting
