Hi everybody,
while trying to debug a serial port issue, I found out some code might seemed
to miss write memory barriers. Does the volatile keyword guarantee that gcc
will no reorder memory writes, or is the attached patched needed ?
Best regards,

This has the relevant updates/additions to the BSP code so that proper
platform_info struct well be passed to the CPM UART drivers. The changes
covered mpc866ads, mpc885ads and mpc8272ads.

Parts of these fixes in 2.4 doesn't seem to be in 2.6.
Maybe these are solved diffrently in 2.6 but I can't tell.
At least cpm_uart_console_write could use this.

Hi all,
thanks for helping me.
Now it works with my configuration.
I added SCC_NUM_BASE as it is without console. And now it works.
#ifdef SCC_CONSOLE
switch (state->smc_scc_num - SCC_NUM_BASE) {
/*SCC_NUM_BASE added*/
case 0:

I use kernel version 2.4.25 of denx and the uart version is
static char *serial_name = "CPM UART driver";
static char *serial_version = "0.01";
Are there newer versions? Sorry, but i am not up to date with the uart.
Is my configura

I don't remember the progress of the new cpm serial driv

Newer drivers don't do this. They are probably stuck in the
linuxppc_devel
kernels and never made it into the main tree. The only problem with
BRGs will be with 8xx, where the ma

on my target (MPC8270, 2.4.25) SCC1, SCC2 and SCC3 will work fine as ttyS0 ..
ttyS2 with console at ttyS0.
It works with this code in arch/ppc/8260_io/uart.c

#define SCC_NUM_BASE0 /* SCC base tty "number" */
#define SCC_IDX_BASE

That is the console port, so take a look at the code for its
initialization for something affected by this configuration.
What kernel are you using? There have been lots of
updates in
Hi,
cpm_uart_cpm1.c doesn't compile due to a missing bracket (linuxppc-2.5

The preliminary UART setup works fine, but when the final

Does anybody have a MPC8260 CPM UART driver that can has been tested with SCC4
