Unified tektool released ! (Firmware flash tools for old Tektronix TDS series)
<< < (20/24) > >>
madao:
this is why: verifty-function is avaible.

Fuma:
Verify function gives the error "Firmware corrupt at address 0x100001" that is the start of Bank 3.
I prefer to load the created dump into a binary file reader program to see what is actually loaded in the memories and bank 3 I only see FF. I'm sure the tektool program is having problems on my TDS540.
Tantratron:
Hello Fuma,
Could you make a close view of the 4 flashfile chips from your processor board ?
When you erase all of them with unified tektool command then read all of them again with tektool, are all the values correctly erased ?

Fuma:
Hello Albert,
for the first question, the scope it opened, what exactly should I see?
Second question, yes of course, all cells are FF.
Today I discovered another problem, there is a difference between Intel and AMD chip. With Intel banks 1 and 2 are programmed with many cyclic errors, while with AMD they are programmed perfectly. To solve the problem on at least one flash card, tomorrow I'll unsolder the 4 chips of bank 3 and I want to try to program them with the willem eprom programmer but I have to make a adapter and a basic program that divides the binary file of bank 3 into 4 files for each chip ( from 32 to 8 bit bus ).
But I would not unsolder 12 chips for the card with chip Intel !
Tantratron:
Hello Fuma, yes I meant that you open your scope, look for the 4 flashfile chips then make a close view picture of the 4 chips. If you make a global view of the processor board, we can then tell you where to find the chips then you make a close view picture. Now it seems you have found the issue if there is a mix of AMD and Intel chips, even though on paper they're interchangeable, in practice wether new or older, their response could be different hence your problem.
