At the moment barebox does not support ARM-Cortex. I suppose there is no problem to port barebox to STM32. However STM32F0 definitely is not a preferred STM32 target chip for porting. Barebox is intended to be a BOOTLOADER. Barebox is intended to load somethi= ng into RAM. STM32F098VC is an advanced STMF0 family chip in terms of RAM and ROM size. STM32F098VC has 256 KB of flash ROM and 32 KB of SRAM. I suppose that barebox can be linked to put code into flash ROM (e.g. see R= OMKERNEL option for blackfin linux kernel port) and 32 KB of RAM can be enough for d= ata but IMHO 32 KB is not enough for comfort and useful work. AFAIR It is possible to run risc-v barebox (both code and data) inside 192 = KB RAM memory space in a VERY VERY MINIMAL configuration, just demo. Barebox can be really useful on linux-capable STM32 chips and board, e.g. STM32F429 DISCO board (https://www.st.com/en/evaluation-tools/32f429idiscov= ery.html) > I couldn't find any mention of such a board in the board support section = of=A0the documentation. > = > I hope I didn't overlook something. -- = Best regards, =A0 Antony Pavlov _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
