bootloader bootcount feature request - Raspberry Pi Forums

-

hello,
i've been working u-boot , pi allow a/b/recovery partition scheme.
u-boot has bootcount , altbootcmd allow booting alternative partition or recovery partition after x boot attempts.

but, i've been struggling u-boot , custom compute module using emmc.

wondering it possible bootcount , altbootcmd feature added default pi bootloader seems have no trouble using our custom compute module , emmc.

around lines of
in fat boot partition file called bootcount.txt with
-------------
bootcount=n
maxbootcount=3
altbootconfig=config_alt.txt
------------------

where:
bootcount increment on each boot, os edit value back 0 on successful boot.
maxbootcount specifies max boot attempt in if bootcount greater number bootloader use config altbootconfig instead of default config.txt


add ability implement recovery partitions.

-dorian

i have nothing bootloader development.

bootloader has ability write (modify) files?
think has implemented reading part simplicity reason.
writing more complicated, because have take care more things.

SD Datastring Convention

i wondering if there preferred convention appending data logged?  see standard sd example uses: code: [select] void loop() {   // make string assembling data log:   string datastring = "";   // read 3 sensors , append string:   (int analogpin = 0; analogpin < 3; analogpin++) {     int sensor = analogread(analogpin);     datastring += string(sensor);     if (analogpin < 2) {       datastring += ",";     }   } creating string called datastring, , appending it, have seen in forums string not liked.  around this, code data logging looks this: code: [select] void sdupdate() {   datetime = rtc.now();   unsigned int hour = now.hour();   unsigned int minute = now.minute();   unsigned int second = now.second();   char datastring[100] = "";   char char_current_pay[15] = "";   char char_overall_pay[15] = ""; ...
