We could argue about whether using U-Boot is cheating, but this chip (OMAP4) boots with a very small internal SRAM and a fairly basic ROM that can copy code to SRAM from various places. Someone then has to configure the SDRAM controller, and I don’t want to do that - so I let U-Boot do it for me.

@thejpster@hachyderm.io I'm trying to remember if the omap4 was one of the TI parts that turned on a watchdog by default. The Davinci series definitely did, and it tended to surprise people who stopped using the factory uboot and thus had to turn it off themselves. So if you try going without the bootloader and get surprise reboots, check.

@thejpster@hachyderm.io Ah, OMAP... That SRAM booting doesn't seem far from Cortex-Ms I worked with 🤔 I configured SDRAM controller myself... then actually never loaded any code in there 😉
