readling, ctrl-u is not working like linux console
Hi, I find it the barebox console's ctrl-u is not working like my linux host. for now, the barebox's ctrl-u discard the whole line. but the linux consle just remove characters before cursor. is the barebox ctrl-u follows any standard, if not, how about make it just works like linux(ah, it is gnu readline) does.

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)
{

+ putchar(getchar());

if (ctrlc()) {

+
net/eth.c
static int __eth_rx(struct eth_device *edev)
{
int ret;
+ if(tstc()) {
+ putchar(getchar());
+ printf("|-_-|");
+ }

the result:

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?

Re: [PATCH] input: add handler for reset and power key input events
Hello, I merged this patch to my barebox. and test on my own board.
1. Abort barebox booting and enter the console.
the board reboots immediately when I press the button without release.
here is my .dts about this button:
net {
label = "board:LED1:system";
gpios = < 1 GPIO_ACTIVE_LOW>;
default-state = "off";
barebox,default-trigger = "net";
};
2. Panic.
type 'go 888' make barebox panic. now I really need a 'reset' key.
I press and releaes the key, and try to hold this key several seconds.
no reaction.
Is the 'reset' key designed for reset the board when something goes wrong?
Regards,
duhuanpeng

mips : How to run barebox by bootm in ram(u-boot command)?
Hello! How to run Barebox from ram now? I have a board with 64MiB ram and 16MiB flash, flash it to the first sector by original u-boot, maybe brick the board. Debrick is difficult due to limited tools. So, I want to run this in ram. And my u-boot *don't* have the "go" command. I have to use bootm command to run Barebox. - - - - - - mkimage -A mips -O linux -T kernel -C none -a 8006 -e 8006 -n 'barebox-tp-link' -d barebox.bin uImage tftpboot 0x8100 uImage bootm 0x8100 - - - - I have try these above, but no luck.

You are running on a board which actually is no mx28-evk, so it's no wonder
it doesn't work. Please mention that next time, because that changes the
question from "What is broken with the mx28-evk" to "What is different on
your board". This is a very important detail to answer questions.
Anyway, you say your board only has 64MiB of RAM, so you must at least
change:
ENTRY_FUNCTION(start_barebox_freescale_mx28evk, r0, r1, r2) {
barebox_arm_entry(IMX_MEMORY_BASE, SZ_128M, NULL); }
to SZ_64M. Other differences might include the pinmux and the UART port
number which is used for console output.

Yes. Which image do you start? It seems you are trying to start barebox.bin. > barebox.bin and barebox-freescale-mx28evk-2nd.img It should be images/barebox-freescale-mx28evk-2nd.img instead. The image should be linked to 0x0, that is right. The code is position independent though and the full barebox relocates itself to the end of the available SDRAM automatically. TEXT_BASE is not relevant here. The start symbol is still 0x even I change TEXT_BASE in menuconfig. my board have 64MiB ram. Modified board. Very cheap one, just 33�. :D EasyARM-i.MX283A http://www.zlg.cn/ipc/ipc/product/id/92.html http://www.zlg.cn/ipc/down/down/id/92.html This board has a LCD(480*800?), I want to test font support on this board. The sch is here: https://drive.google.com/open?id=1_3xW7nfQ6p9tnkjZEDK9vZiLlUnat25K There are many pcf fonts here: https://www.netsarang.com/download/main.html and maybe use code from freetype? http://www.freetype.org/ Sascha -- Pengutronix e.K. | | Industrial Linux Solutions | http://www.pengutronix.de/ | Peiner Str. 6-8, 31137 Hildesheim, Germany | Phone: +49-5121-206917-0| Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917- | ___ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
freescale-mx28-evk run from ram
Dear all, Happy Yuanxiao(Lantern) Festival! I have a modified mx28-evk board, I want to run barebox on it, but I don’t want to make change to the flash. In System.map T __image_start T start T _stext T _text 0004 T __bare_init_start 0004 T get_runtime_offset 0014 t linkadr 0018 T __ld_var_base 0018 T __ld_var__text 0020 t ___text 0024 T __ld_var___rel_dyn_start 002c t rel_dyn_start 0030 T __ld_var___rel_dyn_end 0038 t rel_dyn_end 003c T __ld_var___dynsym_start 0044 t dynsym_start 0048 T __ld_var___dynsym_end 0050 t dynsym_end 0054 T __ld_var___bss_start 005c t bss_start 0060 T __ld_var___bss_stop 0068 t bss_stop So, I load barebox.bin to address 0x: Hit any key to stop autoboot: 0 MX28 U-Boot > tftpboot 0 barebox.bin Using FEC0 device TFTP from server 192.168.12.61; our IP address is 192.168.12.62 Filename 'barebox.bin'. Load address: 0x0 Loading: T # done Bytes transferred = 424776 (67b48 hex) MX28 U-Boot > go 0 ## Starting application at 0x ... I believe the sram is too small to load the binary. So, I change the TEXT_BASE to 0x4160 in menuconfig, build and update barebox.bin, it print funny characters: MX28 U-Boot > MX28 U-Boot > MX28 U-Boot > tftpboot 0x4160 barebox.bin Using FEC0 device TFTP from server 192.168.12.61; our IP address is 192.168.12.62 Filename 'barebox.bin'.
