imx93-lpm: probe of imx93-lpm failed with error -22

[Johan1]

I am running imx-linux 6.6.y and mostly standard u-boot.

I am getting "imx93-lpm: probe of imx93-lpm failed with error -22"

Have traced this to the following (imx93_lpm.c):

	/* get the available ddr fsp info */
	for (i = 0; i <num_fsp; i++) {
		arm_smccc_smc(FSL_SIP_DDR_DVFS, DDR_DFS_GET_FSP_INFO, i,
			0, 0, 0, 0, 0, &res);
		err = res.a0;
		if (err < 0)
			return -EINVAL;
		fsp_table[i] = res.a0;
	}

When I run a precompiled u-boot this succeeds so the problem seems to be with the ddr setup in u-boot. (Or is it the packaged bl31 / lpddrXX training files / mx93a1-ahab-container.img


Where to find the latest fw blobs? all links to these files seems to be broken.

Hi

I would suggest you use the latest bsp 6.6.52.   From the release notes, imx93 evk is tested.
