Re: [U-Boot] setting u-boot params based on serial number

Well I have got it working - but it seems to do exactly what you say it doesn't

for instance

LPNC U-Boot> printenv serialnumber serialnumber=410 LPNC U-Boot> setexpr sn34 ${serialnumber} / 2 LPNC U-Boot> printenv sn34 sn34=208

so it looks like it works ONLY in hex -

yup

a = simple_strtoul(argv[2], NULL, 16); b = simple_strtoul(argv[4], NULL, 16);

I'd like the decimal version like you described :-)

so I've defined setexprd to do that
