Subject: can't interrupt when printing T T T T T
Date: Fri, 30 Aug 2019 00:53:17 +0800 [thread overview]
Message-ID: <20190829165317.GA19424@router.tkernel.org> (raw)
Hello, I boot my barebox by barebox from tftpserver. I poweroff my
switcher. and barebox began to print
- - - -
Booting entry 'net'
T T T T T T T T T T T T T T T T T T T T T T T T T T T T T T T T T T T T T T T T IP 192.168.1.88 is not reachable
- - - -
I try to hit ctrl-c and some other keys. but I can't stop it printing 'T'.
so I added some piece of code to test it
fs/tftp.c
static int tftp_poll(struct file_priv *priv)
{
+
+ if(tstc()) {
+ printf("%s", __func__);
+ putchar(getchar());
+ }
+
if (ctrlc()) {
net/net.c
void net_poll(void)
{
+ if(tstc()) {
+ printf("%s", __func__);
+ putchar(getchar());
+ }
+
net/eth.c
static int __eth_rx(struct eth_device *edev)
{
int ret;
+ if(tstc()) {
+ putchar(getchar());
+ printf("|-_-|");
+ }
+
- - - - - - - -
the result:
Booting entry 'net'

I found it the routine (tftp_poll) didn't catch the key input.
mostly the input is catched by net_poll().
could anyone help to move the ctrlc() dection into the right place?
