Hello,
I am working on trying to get the Azure IoT Hub Demo working on the nRF54h20DK + nRF7002EK.
Currently, i have succesfully loaded the sample on the an nRF7002DK where i have made connection to my IoT hub. This is all working fine.
Now i have tried porting to the nRF54h20DK + nRF7002EK over SPI with the following overlay:
&gpio1 {
status = "okay";
};
&pinctrl {
spi130_default: spi130_default {
group1 {
psels = <NRF_PSEL(SPIM_SCK, 1, 1)>,
<NRF_PSEL(SPIM_MOSI, 1, 5)>,
<NRF_PSEL(SPIM_MISO, 1, 6)>;
};
};
spi130_sleep: spi130_sleep {
group1 {
psels = <NRF_PSEL(SPIM_SCK, 1, 1)>,
<NRF_PSEL(SPIM_MISO, 1, 6)>,
<NRF_PSEL(SPIM_MOSI, 1, 5)>;
};
};
};
&spi130 {
status = "okay";
pinctrl-0 = <&spi130_default>;
pinctrl-1 = <&spi130_sleep>;
pinctrl-names = "default", "sleep";
cs-gpios = <&gpio1 4 (GPIO_ACTIVE_LOW)>;
memory-regions = <&cpuapp_dma_region>;
nrf70: nrf7002-spi@0 {
compatible = "nordic,nrf7002-spi";
reg = <0x0>;
status = "okay";
spi-max-frequency = <8000000>;
/delete-property/ srrf-switch-gpios;
wlan0: wlan0 {
compatible = "nordic,wlan";
status = "okay";
};
bucken-gpios = <&gpio1 0 (GPIO_ACTIVE_HIGH | GPIO_PULL_DOWN)>;
host-irq-gpios = <&gpio1 2 (GPIO_ACTIVE_HIGH | GPIO_PULL_DOWN)>;
iovdd-ctrl-gpios = <&gpio1 3 (GPIO_ACTIVE_HIGH)>;
wifi-max-tx-pwr-2g-dsss = <21>;
wifi-max-tx-pwr-2g-mcs0 = <16>;
wifi-max-tx-pwr-2g-mcs7 = <16>;
wifi-max-tx-pwr-5g-low-mcs0 = <14>;
wifi-max-tx-pwr-5g-low-mcs7 = <14>;
wifi-max-tx-pwr-5g-mid-mcs0 = <14>;
wifi-max-tx-pwr-5g-mid-mcs7 = <14>;
wifi-max-tx-pwr-5g-high-mcs0 = <14>;
wifi-max-tx-pwr-5g-high-mcs7 = <14>;
};
};
Which is working fine, since the WiFi is connecting, however i have a problem which can be seen from my log:

The error -0x2700 comes from modules/crypto/mbedtls/library/ssl_tlc.c where x509_verify_cert() return -9984 which gives the flag MBEDTLS_X509_BADCERT_NOT_TRUSTED
I know the certificate is good, since i used the exact same on the nrf7002dk
I have tried a multitude of different configs and debugging, but i cant see any problems.
All help would be greatly appreciated
