Subject: Imx-usb-loader broken on IMX8MP/v2022.09.0
Date: Sat, 17 Sep 2022 12:04:51 +0000 [thread overview]
Message-ID: <8CA6ADB4-FD4B-4CC8-9BD2-21DA02C08C85@datarespons.no> (raw)
This is observed using straight out of the box v2022.09.0 on NXP IMX8MP Eval kit:
---------
$ sudo ../drimx8/scripts/imx/imx-usb-loader ../drimx8/images/barebox-nxp-imx8mp-evk.img
[sudo] password for hcl:
found i.MX8MP USB device [1fc9:0146]
4 in err=-9, last_trans=0 00 00 00 00
status failed

Stripping off the header gap (32K) allows the binary to load using the standard NXP uuu (Ubuntu 22.04) utility,.
This further raises the question: Why have a header gap at all?
The makes sense for SD card loading, but not for eMMC boot partitions where ROM expects code to start at 0.
Maybe better just use a seek to put the code at the relevant position on the SD card?
For instance, I am using the Rauc boot loader slot update mechanism expecting no gap thus requiring me to shave of 32k
prior to shipping.
Comments??
