Issues in Wilc3000 integarte with BBB #122

Open 20023356 opened 1 year ago

20023356 commented 1 year ago

I am integrating wilc3000 with BBB using Kernel 5.10 ([Debian: Getting Started with the BeagleBone Black]. This version Pin numbers are different from 4.19 kernel version. In 5.10 kernel SPI pin numbers are gpio-78 (P9_31 [spi1_sclk] |P9_31 ) out lo gpio-79 (P9_29 [spi1_d0] |P9_29 ) out lo gpio-80 (P9_30 [spi1_d1] |P9_30 ) in lo gpio-81 (P9_28 [spi1_cs0] |P9_28 ) out lo while booting and insmod wilc-spi.ko i got the following errors

ebian@beaglebone:~$ sudo ifconfig wlan0 up [ 996.034137] power up request for already powered up source Wifi [ 996.044941] WILC_SPI spi1.0: Failed cmd response, cmd (c4), resp (00) [ 996.059352] WILC_SPI spi1.0: Failed internal read cmd...

Please help me to resolve this issue and what could be the issue. Regards Ravi V

Apart from SPI pins connection, the WILC's RESET_N and CHIP_EN pins should be connected with host GPIO's for the power-up sequence. Assuming the SPI is correctly configured, this failure could be because the WILC power-up sequence is not triggered by the host. The details about the power sequence are captured in "4.1 ATWILC Power Control" section of wilc1000/3000 porting guide which can be referred from the link. Host, BBB in this case, GPIO's should be connect to WILC's RESET_N and CHIP_EN pin for chip power-up sequence. Please try connecting the host GPIO's to RESET_N and CHIP_EN if it helps to overcome this issue.

Thanks Ajay

Still the problem is not resolved. I have shared the details in git hub.

So, could you please give me suggestion to resolve this issue. it would you be very much appreciate.

Regards Ravi V

Apart from SPI pins connection, the WILC's RESET_N and CHIP_EN pins should be connected with host GPIO's for the power-up sequence. Assuming the SPI is correctly configured, this failure could be because the WILC power-up sequence is not triggered by the host. The details about the power sequence are captured in "4.1 ATWILC Power Control" section of wilc1000/3000 porting guide which can be referred from the linkhttp://ww1.microchip.com/downloads/en/DeviceDoc/ATWILC1000-ATWILC3000-ATWILC-Devices-Linux-Porting-Guide-User-Guide-DS70005329C.pdf. Host, BBB in this case, GPIO's should be connect to WILC's RESET_N and CHIP_EN pin for chip power-up sequence. Please try connecting the host GPIO's to RESET_N and CHIP_EN if it helps to overcome this issue.

It looks like the first SPI command from the host to the WILC has failed. First, check if the SPI bus communication is working fine. Either validate the Device Tree node entry for BBB SPI device or, If possible, use the SPI bus analyzer to probe the Host(BBB) SPI pins to check whether the command is going out correctly. After the chip ID read is successful, the firmware gets downloaded to the WILC and, then the actual WLAN functionality starts.

Since the first command to read the chip ID failed, just using "ifconfig wlan0 up" should be enough to test this.
Procedure to test: $load driver if its loadable module $ifconfig wlan0 up

If you continue to face issue intergrating WILC with BBB, please open a ticket on Microchip's salesforce portal http://microchipsupport.force.com/ so that respective team can help further.
