Issues flashing CM4 slot 1?

[deosrc]

Describe the bug

When trying to flash a Raspberry Pi CM4 in slot 1 using rpiboot, something seems to be preventing the USB OTG connection.

To Reproduce

1. Connect a USB A-A cable between a machine and the Turing Pi 2.
2. With a CM4 with eMMC memory in slot 1, go to the UI.
3. Power down node 1.
4. Change the USB mode to "Flash" on node 1.
5. Run rpiboot -d ./msd
6. Power up node 1.

Additionally attempted:

1. Connect a USB A-A cable between a machine and the Turing Pi 2.
2. Login to the Turing Pi using ssh.
3. Power down node 1: tpi power -n 1 off
4. Change the flash mode: tpi usb -n 1 flash
5. Confirm using tpi usb status (Outputs usba --> node 1)
6. Run rpiboot -d ./msd on connected machine.
7. Power up node 1: tpi power -n 1 on

Have also attempted running tpi advanced -n 1 msd at various stages.

Haven't yet attempted a different node slot. I will attempt and report back to ensure it is not a cable or connected machine issue.

Expected behavior

• lsusb should show an additional device connected
• rpiboot should detect and push the boot code to the CM4 in node 1

Versions
linux version= Ubuntu 22.04.4
bmc version= 2.0.5
