1. Yes, FAT Partition marked bootable
2. Yes ,BSP User Guide Texas Instruments AM335x BeagleBone Texas
Instruments AM335x BeagleBone Black. This contains details about BSP to be
run on SD Card. Is there any other document detailing loading to Flash?
3. uEnv goes like this
uenvcmd=mmcinfo; fatload mmc 0 81000000 qnx-ifs.bin;go
81000000
4. CCCC says its unable to get uBoot....
https://e2e.ti.com/support/processors/f/791/p/378142/1330741#1330741
Will the steps detailed in the above post is applicable to QNX as well?
Will the IFS generated and used for SD-card will be the same for eMMC as
well?
Thankful for any inputs.
