Our product has a STM23MP151D, no security features (signed stuff or fuses blown) and the same QSPI NOR as the EV1 board.We have run the microcontroller style DDR tester (STM32DDRFW-UTIL) which took a bit of bashing to run on the 151 but did show our...

We quite recently learnt of the move from U-Boot SPL to STM32DDRFW-UTIL and that the MX too would not longer work with the former. That wasted a decent amount of time.The problem is although the code for STM32DDRFW-UTIL is available our PMIC is on I2...

Our hardware has an STM32MP151DAx.In order to make use of the Cube Programmer and the boot-via-USB method I need the equivalent of the tf-a-stm32mp157d-ev1-usb.stm32 file but for our hardware.I have worked through the IOC stuff, have DTS files and go...

The four wire interface from the ST-LINK V2 has no clock.Where does it say that ST devices do not require a clock for SWD ?Also why is it seemingly impossible to work through a hub ? This makes life very difficult.

Yes I have been through this procedure.I'd like to check my understanding of the USB_OTG_HS peripheral as presented in the STM32CubeMX tool. There is a dropdown for "High Speed". Initially I thought with this on "Disabled" it would work at 12Mb/s but...

Literally yesterday my colleague got the tool working on our board. I'm back to TF-A and U-Boot working out where I was before getting distracted with U-Boot SPL earlier in the summer. (Yes there was some holiday and working elsewhere in the interven...

Looks like a mid-high bit is getting corrupted from a noise or timing issue caused by the field itself I should think.Suggest you scope SDA and SCL preferably at a bad bit. This is where an MSO scores.Also check whether the reads were successful.Fina...

I agree. Not working through a hub surely indicates that the ST-LINK is not USB compliant or so flaky is upset by the presence of one. It's a right pain on my setup which is a desktop on the floor.

Yes some possible combinations might but not what I have chosen. Hence stupid interface.

Any design using the STM32MP151 with TF-A/SP_MIN that can be loaded through USB/DFU ?

Changing the I2C bus the PMIC is connected to in STM32DDRFW-UTIL

Where does tf-a-stm32mp157d-ev1-usb.stm32 come from ?

Is SWCLK required for SWD ?

Is it normal for the CubeMX tool (version 6.4.0 and 6.5.0) to suggest there are conflicts for many peripherals where none of these conflicts make sense ?
