Hi metoo0713,

我有几个问题：
1. 无法执行的情况，在整板掉电复位之后是否能恢复？
2. 无法执行的情况，能否给我们提供一下flash status的数值：调用 `esptool.py read_flash_status`
3. (先做完以上两步) 如果重新烧写整个固件，问题是否会消失？
4. 问题是否和开发板/模组强相关，也就是说，如果执行了(2)的步骤，出现过问题的板子是否还会再出现同样的问题？

谢谢！
Michael

Hi GerryTitan, Sorry for missing this. I think we have fixed this issue here: https://github.com/espressif/esp-idf/commit/fd3e28ef0de6196244e7799cffff0d6bf9ea93ec. Could you please take a look to see whether it's fixed? There are also fixes for 4.0 and 4.1 on their latest commit Michael Here is the ...

Hi Omega_fish, 我们在IDF 4.2引入了SPI总线锁（https://github.com/espressif/esp-idf/commit/49a48644e42458366b2dd7b7d153acc943d50e0f），用以仲裁多个SPI设备对总线的并发访问。在此之前，并没有很好的办法防止二者互相冲突。 如果你可以仅在一个task中使用，你可以试试LCD仅使用polling mode，以避免ISR对总线的随机访问。这样两个驱动同时只会有一个访问外设，应该可以避免冲突。*另外一种方式是使用互斥锁（Mutex）避免两个驱动同时访问总线* 同时注释掉这行代码（https://g...

Hi aleix, Another idea, could you try increase `cs_ena_pretrans` and `cs_ena_posttrans` to about 10. See: https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/peripherals/spi_master.html#_CPPv4N29spi_device_interface_config_t15cs_ena_pretransE. Also, I'm not sure if your slave a...

Hi Aleix, I found two more possible issues: 1. The `input_delay_ns` in your device config is 100ns, but that value seems to be 12ns according to its spec. Could you please try setting that value to 0, 10, 12(recomendded), 20 and see what happen? 2. According to the LA waveform, the slave seems to be...

Thanks amruta,

The result is correct, this is an XMC chip.

Thanks for your information, though I haven't got a clue...

Hi aleix, Seen from your data on ESP32 and ESP32-S2, it looks very like there is one bit shift in the bitstream when reading by ESP32-S2. This may be the mismatch between the SPI mode of DM1000 and ESP32-S2. When the SPI mode of ESP32-S2 is incorrectly set, it will fetch the data just during the tra...

Hi @amruta, It's very helpful to know the model of your dev board! But unluckily I don't have that dev board in hand, so I can't debug easily. I'm guessing it's related to the flash in the module, could you please help to run `esptool.py flash_id` to get the flash ID of the module, and post it here?...
