DA16200 not probed in linux

Question

Hi Team, 
 My platform is TI AM62x processor . Linux kernel is 6.1.33, driver version is v5.2.1.2, use the sdio interface 
 After I insert the driver, the initialization function returns 0, indicating that there is no error in initialization. 
 But the probe function did not run . What could be the reason?

Hi St, Thank you for the replies. Yes, for the UART0 you will need 230400 Baudrate. This is mentioned on UM-WI-056 DA16200 DA16600 FreeRTOS Getting Started Guide (renesas.com) , on section 4.4.1 Configuring DA16200/DA16600 Serial debug Interface.

 I have a question to confirm: Is the Flash erase operation mentioned in the Start Guide mandatory? 
 
 Based on the UART0 logs you are using a really old SDK version (which is not supported0 and should have been erased in order to use the Linux Driver. The ThreadX SDK has not been supported since 2020-2021. We officially only support the FreeRTOS SDK v3.2.x.x , the Matter SDK and the Linux Driver . Please follow the steps on 4.1.1 How to Erase Flash and make sure you issue the following: sflash erase 0 400000 In order to erase the whole contents of the Serial Flash. You can verify this with the sflash read command. After erasing the Flash please follow the procedure again. Best Regards, OV_Renesas

Hi ST, Apologies for the delay. Please find the answers from the Wi-Fi Support Team: 1. No. You do not need to rewrite an image. TO run the DA16200 with the Linux driver, the entire contents of the flash memory should be erased first. The linux driver will download the firmware to the DA16200. 2. Without the details of the custom Yocto, we cannot provide exact configurations that need to be ported to a custom Yocto. 3. It seems that the driver cannot get the MAC address from DA16200. We think that the status of the CD pin should be checked to see if it is low or not. To proper operation, the CD pin should be low. Please refer to the user manual on section 4.7.1 UM-WI-059 DA16200 DA16600 Linux Driver Getting Started Guide (renesas.com) If you have any further questions, please let us know.
