TDA4VM_ECO TDA4VM_EVH ospi不识别_a72

请尝试使用最新的processor SDK。
https://www.ti.com/tool/download/PROCESSOR-SDK-LINUX-J721E

你好，此sdk不能在eco的版本中跑起来

e2e工程师需要去问一下，请关注下面帖子的回复。

下载prebuilt包
www.ti.com/.../PROCESSOR-SDK-RTOS-J721S2

ti-processor-sdk-rtos-j721s2-evm-09_00_00_02-prebuilt.tar.gz

将包中的Image-6.1.33-g8f7f371be2 k3-j721s2-common-proc-board.dtb
替换我们的板子中Image ,k3-j721s2-common-proc-board.dtb

然后做交叉实验，发现造成DMA报错的部分在Image

This patch can be easily ported to 8.6. Not much different. Customer can try this on 8.6.

 436: 20230524_14:34:22:850:[ 1.500467] cadence-qspi 47050000.spi: error (____ptrval____): No Rx DMA available

我的意思是，上面这个DMA报错问题，针对dma的patch有嘛，8.6的sdk上是有找不到对应dma的报错的，现在是将9.0的img ,dtb放进去，没有DMA报错，可以将对应的修改项指出来嘛，我们porting到8.6

或者告知一下移哪部分代码，因为遇到很多编译错误

比如一步步移植ti-processor-sdk-linux-adas-j721s2-evm-09_00_01_02\board-support\linux-6.1.46+gitAUTOINC+f8110d9ce8-gf8110d9ce8\drivers\dma\ti\k3-udma.c及相关到8.6，就有很多接口不一样

The above patch is a simple if check patch.

The build errors should be nowhere related to the above patch. If 9.0 is working correctly can they migrate?

这个补丁切过去，没能识别到ospi,

但是我们这边可以用非dma的方式识别到ospi（这可以说明pinmux没有问题）

请看下面e2e工程师的回复。

Have they tried 9.0 SDK and can they confirm if that's working fine?

是我们confirm过
