I.MX RT105x: PXP work abnormal

yourchoochoo — Mon, 21 Jun 2021 02:30:39 GMT

After working on PXP for some time, an IRQ interrupt cannot be received.

When an exception occurs, the registers are as follows

Errors occur with several characteristics：

1. BLOCKX and BLOCKY always is 1，this value is variable during normal operation;

2. IRQ intterupt will not trigger；

3. When error occurring，turn on and then trun off SFTRST bit for softreset PXP，it cannot resume normal operation .

Hi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
I was wondering if you can illustrates the testing steps that can replicate the issue, as I'd like to get more infromation.
Have a great day,
TIC

Environment: 8M flash XIP, 32M SDRAM

Using 800*480 LCD（ARGB8888） to display GUI,and use pxp to achieve blend and rotate operation frequently；

after 1-3 hours long time work, PXP will work abnormal as described above.

Hi,
Thanks for your reply.
Whether you can replicate the phenomenon on the MIMXRT1050-EVK board, If yes, please share the code, then I can give it a try.
Have a great day,
TIC
