I'm interested in if there is a way to disable the Serial Downloader Mode fallback. In other words, unless the BootMode is set to 1, I would like the device to essentially do nothing if the internal boot mode fails.
From reading the RM, and especially from seeing the high level boot code flow diagrams, this doesn't particularly seem possible. Primarily, I'm basing my conclusion on Figure 9-1 in chapter 9.3.2, and figure 9-19 in chapter 9.11 of the i.MXRT 1060 RM, which appear to show that all boot modes lead back to Serial Downloader mode when everything fails. However, being quite new to this, perhaps I've missed something.
If you need any elaboration or further detail, let me know.
Thanks
Hi @Bless4250 ,
I agree with your understanding of boot flow that the disabling on serial downloader fallback you mentioned cannot be done, which has solidified in BootROM. Unless serial download mode is completely disabled by eFuse, this shouldn't be what you need either.
Best regards,
Gavin
