More Info on Driver Writing and Debugging

All the articles have been recently reviewed and updated, and are written using the clear and definitive style you've come to expect from OSR over the years.

Protect windows from DMA to illegal RAM area

zviveredzvivered Member Posts: 65


The FPGA is initiating DMA to contiguous buffer (AllocateContinuousPhysicalMemory in attached Init.txt)
The driver writes physical address and size to registers in FPGA in order to initiate the DMA.

Due to a firmware error, after a while the data is written to an area outside the pre-allocated buffer.
If this happens, the PC hangs or we have a blue screen with a message (each time different message)
Is it possible to protect windows some how from such case ?
The goal is to catch the moment that FPGA is trying to do such thing.

Thank you,
