TDA4AL-Q1: How to modify env parameters of uboot in QNX?

Namic Chang

Part Number: TDA4AL-Q1

Hi, TI experts:

I would like to change the parameters of ENV in UBoot for QNX, how can I do ?

For Linux, it has envtools (fw_printenv/fw_setenv) to access, but for QNX, does it have similar tools ?

Thanks,

Best regards,

Hi Namic,

For booting to QNX using Uboot, any uboot environment changes are done at the UBoot level for the PSDK QNX delivery.

The TI PSDK QNX, does come with an example uEnv.txt

Hi,

I am also interested in knowing this, i.e, modifying/reading u-boot environment variables from QNX, just like how we could do it from Linux using fw_setenv/fw_printenv(https://source.denx.de/u-boot/u-boot/-/tree/master/tools/env?ref_type=heads).

Booting to QNX through U-boot is fine, but how to access U-Boot's Environment Variables from QNX is the question.

Best,
Moses

Hi Moses,

Regarding "but how to access U-Boot's Environment Variables from QNX is the question.", this question should be directed to QNX Software Systems.
