Hi, based on André recommendation I commented out the PS1 variable and now I get `-sh-4.4#` for the prompt. I also checked and nothing is overwriting the variable.
But I tried to change the size of the shell by using `stty cols 100 rows 40` as well as different sizes (smaller and bigger than 80 columns), but the amount of characters I get on the line stays at 81 followed by carrige return. However if I record the session with `script` I get the correct amount of characters per line. Here is my `stty -a` output: speed 115200 baud; rows 24; columns 100; line = 0; intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>; eol2 = <undef>; swtch = <undef>; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R; werase = ^W; lnext = ^V; discard = ^O; min = 1; time = 0; -parenb -parodd -cmspar cs8 hupcl -cstopb cread clocal -crtscts -ignbrk -brkint -ignpar -parmrk -inpck -istrip -inlcr -igncr icrnl ixon ixoff -iuclc -ixany imaxbel iutf8 opost -olcuc -ocrnl onlcr -onocr -onlret -ofill -ofdel nl0 cr0 tab0 bs0 vt0 ff0 isig icanon -iexten echo echoe echok -echonl -noflsh -xcase -tostop -echoprt echoctl echoke -flusho -extproc Best regards Petr hodina ‐‐‐‐‐‐‐ Original Message ‐‐‐‐‐‐‐ On Wednesday, September 18, 2019 4:13 PM, André Castro <andre.castro...@gmail.com> wrote: > Hi Petr, > > I still don't think this is related to Yocto. > Comments below. > > Best regards, > André > On Wed, 18 Sep 2019, at 02:17:01 PM (WEST+0100), Phodina wrote: > > > Hi, > > so I tried the PS1 prompt as suggested by André and it worked at that time > > on the booted system.
