【已解决】S2 SPI MASTER assert(desired_dev) 问题

[ppacctv]

idf master 5.2

driver/spi_master.c 729 行
assert(desired_dev)出错

驱动lcd，大概4月份git更新master代码后，发生错误，将assert(desired_dev)注销，错误消失。

assert failed: spi_intr spi_master.c:729 (desired_dev)

你是从哪个版本升级到master分支的，代码是不是还是复用的原来分支的。
LCD在 v5.0 做了一些改动 （https://docs.espressif.com/projects/esp ... s.html#lcd）， 建议你们直接基于master 分支的 demo进行测试

[fanatmeta]

我们这边观察到同样问题，LCD 随机出现（和 timing 有关）

Code: Select all

D (3089) lcd_panel.st7789: new st7789 panel @0x3fc9cd9c

assert failed: spi_intr spi_master.c:651 (desired_dev)

代码基于的 master 分支的，这个看起来像是锁竞争？按理说 SPI 中断内 desired_dev 怎么会变呢？

我发现 SPI 驱动的工程师已经在 github 上推送了一个 fix 方案 （https://github.com/espressif/esp-idf/co ... 05f7290a1f），请问问题目前还存在吗

[fanatmeta]

Already fixed on master
