We have noticed an unusual problem with EasyInstaller. We used the Verdin devices without Wifi and re-use the Wifi pins. During Easyinstaller boot it looks like MSP_15/SAI1_TXFS is getting set high.
Unfortunately for us this happens to enable PoE which some switches don’t like causing the current limiter to reboot us during programming.
Can anyone confirm why MSP_15 gets set high? If it needs to? And if EasyInstaller knows it is on a board without WiFi?
EasyInstaller is pre-installed on the SOMs and I think this is the version string: U-Boot 2018.03-toradex_imx_v2018.03_4.14.98_2.3.0_bringup+g52f89f8382
I should say that maybe we don’t see this behaviour with new versions of EasyInstaller that we apply using recovery mode.
the MSP_15/SAI1_TXFS is the SOM X1 Pin 120. This one is connected straight out the the module’s edge connector from the SOC.
So it is not hardware related to the missing Wifi module.
So on the Software site, this could be during Uboot or OS that pin gets set high.
Timing wise when does the signal go up?
somehow the uboot and kernel version you are mentioning doesn’t match that minimal supported BSP for the verdin. Which module version we are talking about here?
Hi @matthias.tx,
These are all 1.1b but probably supplied quite a while ago now. For example one of the parts with this issue is serial number 07021921. Are you able to look up what that was programmed with before it shipped to us?
Ed
the easiest way would be to recover these modules to the newest Toradex EASY Installer.
Current Modules should be shipped with Toradex Easy Installer - 5.6.0
What is the exact model number of you verdin module?
We checked and on this particular older module ToradexEasyInstaller_2.0b7 had been preinstalled.
Please use the recovery mode to load and then flash the ToradexEasyInstaller_5.6.0 on it.
Thanks for letting us know. We already have a workaround in place but good to understand what has happened. This did cost us about a week of production time to figure out though.
