器件型号：OCTVO-3P-AM335X
主题中讨论的其他器件：AM3358

您好！

我一直在尝试让 SPI 在基于 am3358的 OSD3358-512M-BAS 上工作。我尝试 spidev_test 以检查是否正常运行、但看不到预期输出。测试结果如下：

debian@beaglebone:~$ ./spi/spidev_test -D /dev/spidev0.0 -v
spi mode: 0x0
bits per word: 8
max speed: 500000 Hz (500 kHz)
TX | FF FF FF FF FF FF 40 00 00 00 00 95 FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF F0 0D |..
....@.........................|
RX | 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |..
..............................|

我一直在尝试使其能够修改此页面上的此链接提供的 DTS 文件。

检查 DTS 文件的附件。

我在这里循环浏览了多个论坛问题、但我不幸运、我不确定我错过了什么。请告诉我为使其正常工作而应进行的更正。

Abhishek、您好！

您在 AM335x 上运行的软件版本是什么？

TI 仅支持有关 AM335x Linux 处理器 SDK 中分发的 Linux 版本的问题。您是否已联系 Octavo 获得使用其软件分发的支持？

此致、

Nick

您好、Nick、

我在主板上运行 BeagleBoard.org Debian Image 2018-10-07、内核版本为 4.14.71-ti-r80。我还没有就此联系 Octavo。
