Hi! I recently bought the XPORT version of the FlashcatUSB to program some memory chips. These are the NOR Parallel Flash M29W160ET.
My FlashcatUSB PCB is version 1.1 and i have upgraded its firmware to the latest 4.37 XPORT firmware.
Chip is a TSOP-48. The jumpers are correctly configured on the Extension I/O Port at 29 position, that is on the right for all three jumpers.
The software detects the memory chip correctly.
The memory chips that i bought from a chinese supplier were already written with a firmware image that appears to be a Sharp TV firmware. I want to erase the chip.
When i try to erase the chip, the proceedure appears as it has been completed successfully but the chip isn't really erased as the previously written contents are still there.
When i am trying to write my own binary to the chip, it fails to erase each memory sector. A window pops up saying "Flash Erase Failed".
Is this a FlashcatUSB hardware/software problem or are the memory blocks protected? And if the chip is protected, shouldn't the software issue the appropriate commands to unlock and program it?
Also is there a chance that the chip is factory locked? The codes on the chip read:
ST M29W160ET - 70N6 L (what does this L mean??? - i haven't found any explanation in the documentation and datasheets - perhaps factory (L)ocked???)
Thanks in advance!
