Hello,

I use an evaluation board Raisonance REVA 2.10 and a STR912F daughter board.

The CPU chip is a STR912FW44X6 with number 625 (Rev D silicon).

I work with the STR9 V1.2 library New Release.

I use UART0 transmition with Tx and Rx interrupts.

In addition, I use the timer0 interrupt to blink LEDS on GPIO6.

When I use only UART0 the transmission works fine.

When I use only TIM0 the leds blink fine.

The problem being when I enable UART0 and TIM0 together :

transmission still works, but the leds blink in a random way.

I read similar problems on this forum, but I acknowledge, I don't understand what is necessary to change.

I have attached my Source-Code.

Please, help me !

Philippe
