We have plan to use the BW2455-44P (sdio/dhd-android-1.363.125.19 <driver> ) with Sigma Star SDK(SAV837SDK_V15/Linux(kernel) version : 4.9.227).

The command(ping) is worked fine after connecting to AP.

Howerver, When I tried to do live view stream with VLC on the PC after the unit connected to AP(Router, The PC and unit are in the same nework), There was Cmd error ( [sdmmc_1] Err: #Cmd_53 (0xA900004A)=>(E: 0x0100)(S: 0x00000000)__(L:1059)(B:74/74)(I:0/1) dhd_bcmsdh_send_buf: sdio error -1, abort command and terminate frame).

- So, Could you help me how to fix the issue as soon as possible ?

- Please let me know which driver I should use to fix the problem.

Hi @ChadCha,  we saw a similar issue on FMAC on the SIGMASTAR platform -> https://community.infineon.com/t5/AIROC-Wi-Fi-and-Wi-Fi-Bluetooth/What-is-the-cause-of-SDIO-CMD-52-e...

I am checking internal if we have a fix for DHD. will get back to you on this

Dear Vivek, 

We are using  the driver (dhd-android-1.363.125.19/https://drive.google.com/file/d/1y_wJshoDnximS5Ak3NrHEDfgYoQzhs3e/view?usp=sharing ) that provided from  micro networks in south korea. The revised content that linked on the previous comment(Jul 29, 2022 04:06 AM) could not be applied to the our system because the code contents is different with the driver (dhd-android-1.363.125.19).  And We tried to fix the issue using the driver included in the SDK (SAV837SDK_V15/https://drive.google.com/file/d/1h0lC7Tq2_V5k80sh8Pcg4q_zkFgGtfFf/view?usp=sharing ), but the driver did not work properly like below. That is becacue we can apply the revised content that linked on the previous comment(Jul 29, 2022 04:06 AM)

So, Could you tell me how to apply it after compiling the driver file included in the SDK ?
