Stm32mp157a-dk1 - U-Boot 2019.10 SPL hangs at start-up

Hi all.
I have a STM32MP157A-DK1 board and I am following the instructions of the related wiki to get a working Linux system.
I followed the instructions but when I power-on the board I get

U-Boot SPL 2019.10-rc1 (Aug 26 2019 - 14:17:53 +0200)
Model: STMicroelectronics STM32MP157A-DK1 Discovery Board
RAM: DDR3-1066/888 bin G 1x4Gb 533MHz v1.44
WDT: Not found!
Trying to boot from MMC1

and then the system hangs.
Searching this forum I found this message in which the problem was solved simply recompiling u-boot using the compiler used in the wiki but this is not working for me.

Could you give me any suggestion? Thanks!

@dbicego try a 2nd microSD card or rewrite the microSD again. It’s also happened once for me, but i haven’t been able to reproduce it enough to analyse it…

Can I assume you are NOT using a VM solution like recommended? (VMware/VirtualBox/etc…)

@RobertCNelson Thank you for your reply.
I tried to rewrite the microSD many times but nothing changed.
Actually, I AM using a virtual machine as build system because on the PC that I can use I haven’t a native Linux system.
Could my error be related to that? For some other jobs I used some tools to generate embedded Linux using virtualized build systems and all went fine.
Did you find that building on a virtual machine have impacts (apart from performance obviously)?
Thanks again for your help.

@dbicego, Virtual Machines are not supported due to the very issue you are seeing. They do not correctly write the bootloader via dd to the microSD, thru their emulated usb interface.

@RobertCNelson Ok, so I guess that I have to find a Linux native machine to try to fix this.
I’ll be back soon with an update.
Thanks for your explanation!

Hi @RobertCNelson, I managed to do all the procedure with a Virtualized Linux except for the “dd” part of the bootloader that I did using another board running native Linux.
Like you said, this solved my problem and now I have a running Linux on my STM32MP1 dev-board.
Thank you for your help.
