Bootloader issue on MIMXRT1176

Hi,

I am working on bootloader in MIMXRT1176-EVK and referred these two examples for OTA update through bootloader.

Eg 1 : "mcuboot_opensource"

Eg 2 : "lwip_httpscli_ota_enet"

I tried on "led_blinky.bin" upload through OTA update, its working fine but, I tried on "sd_jpeg.bin" it's not working.

I assuming that "sd_jpeg.icf" needs to change according to the"lwip_httpscli_ota_enet.icf".

Please find the attachments below.

Can you help me this issue?

Thanks.

Hi @smartpavan333 ,

The sd_jpeg.txt put code in ITCM and data in SDRAM. But the opensource_mcuboot will not copy code to ITCM and will not initialize SDRAM. So you must add these function to it.
