That outputs LLC about a second after the mxsldr terminates (kinda slowly, the individual characters can be seen being emitted one at a time), and then about 5 seconds later, "Pref". But nothing after that point.
At least it looks like there is something happening, which is excellent! Thank you! Without CONFIG_SPL_MXS_PMU_ENABLE_4P2_LINEAR_REGULATOR=y, (i.e. all 3 PMU options not set) I still get the LLC\nPref as previously. With only CONFIG_SPL_MXS_PMU_MINIMAL_VDD5V_CURRENT=y, I get LLC\nPref With only CONFIG_SPL_MXS_PMU_DISABLE_BATT_CHARGE=y, I get LLC\nPref With only CONFIG_SPL_MXS_PMU_ENABLE_4P2_LINEAR_REGULATOR=y, I get LLC\nPref With CONFIG_SPL_MXS_PMU_ENABLE_4P2_LINEAR_REGULATOR=y, AND: - CONFIG_SPL_MXS_PMU_MINIMAL_VDD5V_CURRENT=y, I just get a single L. - CONFIG_SPL_MXS_PMU_DISABLE_BATT_CHARGE=y, I get the LLC\nPref as previously. With CONFIG_SPL_MXS_PMU_MINIMAL_VDD5V_CURRENT=y AND CONFIG_SPL_MXS_PMU_DISABLE_BATT_CHARGE=y, I get LLC\nPref With all three =y, I just get L Rogan On Mon, 25 Sept 2023 at 17:50, Fabio Estevam <feste...@gmail.com> wrote: > > On Mon, Sep 25, 2023 at 11:00 AM Rogan Dawes <ro...@dawes.za.net> wrote: > > > I see absolutely nothing in the console. > > > > I’m wondering whether I can possibly execute the vendor SPL with a modern u-boot? > > The old U-Boot vendor does not use SPL.
