Why does the BILINEAR_INTERPOLATION crash？

[Jack li1]

Hi all:

I'm using TextureMapper now if i used BILINEAR_INTERPOLATION will crash.There is no problem if you use NEAREST NEIGHBOR.As shown in the picture below:

Exceeding some buffer boundary? Running out of heap space?

A register dump from the Hard Fault Handler and a Disassembly of the faulting instructions would be illuminating..

Both increased still crash

Ok

Perhaps do some investigating as to the reason behind the hard fault as Tesla suggests. There is a significant amount of information in the SCB registers.

The PC pointer is 0x00000 and the LR register points to the inside of GFX.What is the problem that can't be analyzed at present.I can't analyze what happen at pressent

[Jack li1]

My question is why does changing the algorithm cause a crash?

[TDK]

Do the PC and LR register values help solve this problem?

[Jack li1]

Both point to the GFX library

Hi,

Were you able to solve your issue ? Which mcu are you working with by the way ? What version of TouchGFX are you using ? Which toolchain/IDE as well ? Could you maybe share your project or explain how to reproduce it if easy to do so ?
