I can write down the com4 and com6 into the COM selection box in the Terminal1 settings window, but it returns "no such port.." when trying to connect actually - see below. It also locks the com4 driver down so I cannot open the com4 w/ the TeraTerm after such above attempt (I have to powe...

I am using BT modules for comm with my discoboards. When trying the built-in Terminal1 (CBS5), ie. com4 or com6 (my two BT modules) it says no coms, and locks them, so even TeraTerm says coms are not available. Disconnecting/connecting the st-link helps (so TT can use them again). Any hint how to se...

Including the following code into my source causes the system halts around i2cstart (it works in trunk).. If somebody may see an issue below, give me a hint , plz :x .. #include "chTinyRTC8563.h" .. static const I2CConfig i2cfg1 = {OPMODE_I2C, 400000, FAST_DUTY_CYCLE_16_9}; //40Mhz clock ....

Ah, yea, tickless mode requires a hw counter.. thanks.
The next step is the I2c..

I have a task, which does: static THD_WORKING_AREA (waThread1, 128); static THD_FUNCTION (Thread1, arg) { (void)arg; chRegSetThreadName("counter"); // Time for next read. systime_t wakeTime = chVTGetSystemTimeX(); while (TRUE) { wakeTime += 10; chThdSleepUntil(wakeTime); seconds_counter++;...

It started to work somehow, but: 1. when I2C stuff enabled it crashes in an unhandled exception (I will investigate) 2. getting compile error: 'RDY_OK' undeclared here (not in a function) usually returned by i2cMasterTransmitTimeout() - is being lost somewhere, so I have to def it in my source as 0 ...

LTO disabled: text data bss dec hex filename 17364 428 4528 22320 5730 build/ch.elf 2kB less, do I miss something there? Still hangs on the I2C.. I removed the I2C stuff, printing some adc values and systime, ( with spi, adc, and pwm chunks from demos) in a loop. It does few loops, prints, then stop...

In RT-STMF100-DISCOVERY there is probably wrong def MCU = cortex-m4 What I do not understand yet is my compiled code under 3.0 is 5kB smaller than with trunk.. :shock: 3.0: text data bss dec hex filename 14384 428 4528 19340 4b8c build/ch.elf trunk: text data bss dec hex filename 19492 356 4416 2426...
