TCM loading address for i.MX 93

Josh-256 — Tue, 30 May 2023 12:49:41 GMT

I am working with imx93 (IMX9352CVUXKAA) and I would like to bring up the Cortex-M core

I have been using the SDK imx9>93> MIMx93xx>MIMx9352xxxxK from the website and have successfully compiled the hello_world sample app.

From the Uboot I would like to load the hello_world.bin into the TCM memory location. Unfortunately, I am not sure which address I must use. I have tried address 0x20020000 and 0x20000000 etc. as stated in the table from imx93 reference manual. But leads to crashes and board restarts

Could anyone point me to the correct address to use?

Hi @Josh-256

Have you tried bootaux 0x201e0000

Best regards

Hi @Harvey021

Yes, the address 0x201e0000 no longer gives me a crash.

Used the set of commands as shown below

fatload mmc 1:1 80000000 hello_world.bin
cp.b 0x80000000 0x201e0000 0x10000
bootaux 0x201e0000 0

How did you get this address? I saw this in the documentation of the SDK but could not relate it to the datasheet.

I tried to run command bootaux 0x201e0000 0 in u-boot and got the following:

Image's address 0x201e0000 is invalid.

Is this valid only for LPM boot?
