Hello all,
I am using the Application Timer (as written in https://devzone.nordicsemi.com/nordic/short-range-guides/b/software-development-kit/posts/application-timer-tutorial ) in my Embedded Serial File System (JesFs, Open Source and free for everyone)
On SDK16 everything runs perfectly, reliable and stable on several hardware platforms (PCA10056, NINA-B3 (u-Blox) and others).
On SDK17 I found the APP_TIMER not running (same software, no changes, I tested it with SES 4.20 and 4.50 on PCA10056).
The problem shows easily in "/platform_nRF52/tb_tools_nrf52.c -> tb_delay_ms()" , if the UART_TX_BUF_SIZE is small, so that the putc-function must wait (as shown in line 123 of "tb_tools_nrf52.c"):
- Clone https://github.com/joembedded/JesFs
- A complete working project for PCA10056 and SES is in "/platform_nRF52/pca10056/ses/JesFsDemo_pca10056.emProject"
- The projects will show a text console on the standard UART, e.g.: '!' shows the time, 's2' sleeps for 2 seconds, etc..
- SDK16:

Thanks for your help!!! I have NO idea any more where to search for....
