I have a question about i.MX6UL SD/MMC Manufacture Mode chapter 8.12 of IMX6ULRM Rev. 1, 04/2016.
My customer have some boot problem in their custom board with i.MX6UL.
It seems that their custom board boot up in SD/MMC Manufacture Mode when it try to boot in Serial Downloader mode.
According to the Figure 8-27, when SD/MMC MFG mode enabled, it goes to SDMMC MFG mode boot.
When SDMMC MFG mode boot, which BOOT_CFGx setting does i.MX6UL read ?
I found the thread about SD/MMC Manufacture Mode in i.MX6DL as follow.
What boot config is applied if i.MX6SDL enters SD/MMC Manufacture Mode?
However, I can't clarify from the thread so please tell me.
