Hello,
I'm currently looking to update my device using a file I have stored on my SD card. I am currently using SD.h to manage my files on my SD card.
When I try to update the firmware using Update.h by inputting a SDLib::File of the firmware it does not work. I get a return false when it came to the ESP_IMAGE_HEADER_MAGIC. I'm not sure why as the file I'm opening is "correct".
When I looked at the example provided by espressif in the library, I saw they were using SD_MMS.h instead of SD.h. I wasn't able to make it work.
E (96) sdmmc_cmd: sdmmc_card_init: send_if_cond (1) returned 0x108
[E][SD_MMC.cpp:68] begin(): Failed to initialize the card (264). Make sure SD card lines have pull-up resistors in place.
Card Mount Failed
So my question is why was SD_MMS.h used instead of SD.h? and is SD_MMS.h the correct library to use to perform an update?
Thank you for your time.
