GPU GC355 not responding and it got stuck.

[sathishkumarsig]

Hi,

How I can ensure whether the GPU gc355 in vybrid processor is executed all of the commands in the command buffer(0x400CF500)?

In Vybrid_Reference_Manual_F_Series_-_Rev_3.pdf, it is mentioned that the GPU will generate the interrupt after all the IDLE bits goes high and INTR enabled.

If i consider the idle register(0x400CF004) status, sometimes it is having 0x7ffff7fe instead of 0x7fffffff/e.

The Clock Control Register (0x400C_F000) having 0x00040100 instead of 0x00070100 for longtime.

Is there is any error status register to find out the reason why the commands are not get processed?

Please support.

Hello Sathishkumar,

The Vybrid Tower platform currently does not have GPU support. It seems you are looking at an older revision of the reference manual - the current revision (VYBRIDRM) is here, with no reference to the gc355 chip:

Hi Timesys Support,

Thanks for your reply. The Micro chip placed in the Faraday EVB is PVF522R3K1CMK4.
