Experience with SFP programming in v1.9.2

Postby zburget » Wed Aug 20, 2025 4:18 pm

Hi,
I found and install new version of Revelprog-IS and try it for SFP programming.
I've a few comments/experiences:
  1. Fixed bug - removed warning message about checksum error in A2 block - THOUSANDS OF THANKS!!!
  2. There is no need to click "Execute" in Password tool window to send a write password to the module. But… Sometimes it happens that the writing operation fails (as the password has not been sent). Just start the write process again and will be successful. I couldn't find out why and when it was happening.
    If there is no need to send a password using the "Execute" button, what is the button there? Wouldn't it be possible to remove it? Or is it used to change the password?
    It would be nice to place somewhere on the main window CheckBox "Send Password" or "Use Password" or somehow similarly. I have modules where the password MUST be used to write the block A0, and MUST NOT be used to write the block A2. It's always unpleasant to switch between the windows for this setting.
    Would it be possible to add a non-standard password location address to the list? It doesn't have to be hardcoded in the program, it would be ideal if I could add an item to the existing list. In my modules is the address of the entry of the password A2-FCh. It is disgusting if I always must to manually rewrite it and I can't select from the list.
  3. But the problem is with the data writing to the module! In version 1.9.1 the data was written very quickly, 1 - 2 seconds. In the new version it is very slow. In the log, there are always a few lines logged quickly, then waiting for a while, then a few lines in quick sequence, then waiting for a while,… Even the number of written blocks in quick sequence is not always the same. Sometimes it is 10 lines, sometimes 15, sometimes only 3, sometimes only one. Mostly less than more. Writing of block A0 lasts ideally about 10 sec, but normally even 25 sec !!
    Am I doing something wrong? Do I have sets something wrong somewhere?

And one more small thing to improve in the next version:
I have passwords saved in a table for different types of SFP. When I try to copy the password into REVELPROG, it behaves strangely. I'm not allowed to copy hexacodes, but the corresponding ASCII characters, which are entered into the password fields as hexacodes. However, it is not always possible, quite logically, to copy ASCII characters.
