ChibiOS Free Embedded RTOS

Hi !

One day, One problem.

Today I look for writing a Gfx driver for my ssd1322 Oled display.

May be I say bullshit but this is what I have understand about the display :
- The display have a 4 bpp depth, so I need to have 2 pixels for sending one data byte.
- Worst : Columns are addressing 4 by ...

I have my problem ! I used a uint8_t * for the returned number of written bytes instead of uint16_t *

Now It work perfectly

Thanks for help ! Goto Next step

I like gdb, I can see thread free memory now.


Breakpoint 1, sWriteToFile (_this=0x2000087c, logLevel=Error, fmt=0x8030a84 "SD Card mounted", ap=...) at Log/file_logger.c:184
184 FileLogWriter *flw = (FileLogWriter*) _this;
(gdb) n
186 __CHECK_AND_ROLLBACK(flw);
(gdb)
191 ...

Ok I have seen the linker script, but I think 1024 bytes is enought.

At this point, my main thread and logger thread can open files but can't write in it. (no hang, fs_type from file descriptor and device don't match). So I go back to my problem.

Unfortunately DrunkenDonkey, I haven't windows ...

Yes there is a difference, I have changed the logger stack size :

-O2 :
ChibiOS/RT Shell
ch> mem
core free memory : 73848 bytes
heap fragments : 1
heap free total : 512 bytes
wa_logger_daemon total : 1199 bytes
wa_logger_daemon free : 884 bytes
wa_lwip_thread total : 612 ...

I have some news.

So I just added a small opening/writing code in the main thread of ARMCM4x_STM32F407_LWIP_FATFS_USB and it works (with "0:/test.log" and "test.log")

Then I have sripped all my modifications in my project (based on ARMCM4x_STM32F407_LWIP_FATFS_USB too) but I miss something because ...

I can accept that, but it is not a custom board, I think Olimex test their board ?

And why can I list file on SD ?

This is the origin :

Hi,

I have another little problem. I work on a file logger and I can't open a file, I just completed the InsertHandler for ttsting purpose :

static void InsertHandler(eventid_t id) {
FRESULT err;

(void)id;

just call the httpd_init() function in the thread.
