nrf54lm20a OTA fail

[john.liu]

Hi:

I use sdk ncs3.3.0 and nrf54lm20dk.

CONFIG_DFU_TARGET=y
CONFIG_DFU_TARGET_MCUBOOT=y

Failed to return using AA dfu_target_init.

OTA firmware is zephyr.signed.bin.

                    LOG_HEXDUMP_INF(&pkt->data[3], MIN(data_len, 16), "DFU header");
                    LOG_INF("data_len = %u", data_len);
                    enum dfu_target_image_type type = dfu_target_img_type(&pkt->data[3], data_len);
                    int err = dfu_target_init(type, 0, total_size, NULL);
                    if (err) {
                        LOG_ERR("Failed to initialize DFU target = %d", err);
                        return;
                    }

Hi!

Try this:

Add to the application's prj.conf:

CONFIG_DFU_TARGET=y
CONFIG_DFU_TARGET_MCUBOOT=y

 
CONFIG_FLASH=y
CONFIG_FLASH_MAP=y
CONFIG_FLASH_PAGE_LAYOUT=y
CONFIG_STREAM_FLASH=y
CONFIG_IMG_MANAGER=y
CONFIG_MCUBOOT_IMG_MANAGER=y

--

And in sysbuild.conf:

SB_CONFIG_BOOTLOADER_MCUBOOT=y

Hi Sigurd:

Thanks for your help!

I have made the modifications, but there are still issues.
