danielappiagyei-bc commented on issue #10912: URL: https://github.com/apache/nuttx/issues/10912#issuecomment-1763226964
I have a [PR](https://github.com/apache/nuttx/pull/10911) up which fixes the overrun in `imxrt_dma_nextrx()`. The other half of the fix which I haven't included in the PR is to place the `g_lpuart{1-8}rxfifo` into TCM. It fixes the issue but what I don't understand is why our call to `up_invalidate_dcache()` [here](https://github.com/apache/nuttx/blob/master/arch/arm/src/imxrt/imxrt_serial.c#L2724) isn't sufficient. @davids5 @xiaoxiang781216 Do either of u have any thoughts on what's going on? -- This is an automated message from the Apache Git Service.
