I changed it to: CONFIG_BOOTCOUNT_LIMIT=y CONFIG_SYS_BOOTCOUNT_MAGIC=0xB0C4 CONFIG_SYS_BOOTCOUNT_ADDR=0x30370090 CONFIG_SYS_BOOTCOUNT_SINGLEWORD=y and now bootcount increments. Thanks, Fabio Estevam

It works as expected, and the "bootcount" environment variable gets incremented after a reset. Good! However, if I try the same on an imx8mn_evk, the "bootcount" variable always stays at 1 and never increments. Uff... environment code should be independent from the board... Do you happen to have any idea as to why imx8mn behaves differently in this aspect? saveenv works on the board? Does it use protected Environment? No more ideas ... sorry... bye, Heiko -- DENX Software Engineering GmbH, Managing Director: Erika Unter HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany Phone: +49-8142-66989-52 Fax: +49-8142-66989-80 Email: h...@denx.de
