Error in buildroot-external-st (RTC, WLAN) #40

Closed MarioPieschel closed 1 year ago

MarioPieschel commented 1 year ago

Error in buildroot-external-st, branch 2023.02.2. The result is that the WLAN will not work. In branch 2022.02.7 the RTC is initialized correctly, and WLAN works.

My board is the STM32MP135F-DK, MB1635B. With this configuration: st_stm32mp135f_dk_demo_defconfig.

dmesg | grep rtc [ 3.084346] stm32_rtc 5c004000.rtc: rtc_ck is slow [ 3.187767] stm32_rtc 5c004000.rtc: Can't enter in init mode. Prescaler config failed. [ 3.194423] stm32_rtc: probe of 5c004000.rtc failed with error -110

Hello, thanks for reporting the issue. Indeed there is an issue with the devicetree TF-A generated by Cube MX. The devicetree node "rcc" is wrongly set. I am reporting the issue to ST and will fix it soon. meanwhile, you can import this devicetree in the Buildroot external instead of the one generated by CubeMX.

ST raised a ticket on this issue. I will add the devicetree fix in the next release.
