XUF232-1024 stalls after software reboot
Posted: Thu Aug 05, 2021 8:40 am
Hi everyone.
Chip is XUF232-1024-FB374-C40 as tile[0-3] and second XU208-256-TQ64-C10 as tile[4]
I'm stuck with software reboot issue. The reboot code, which executes on tile[0], was taken from module_usb_audio for this chip and previously was used for device reboot to enter into DFU mode.
We have two devices and on the first one it works perfectly, but the second one can stall at 10th-20th reboot.
The device resets for sure, but stalls for unknown reason. It can be seen by probing QSPI CLK pin X0D10
Here you can see CLK signals when device boots up normally.
But here device stalls. In that case only hard reset or power reset helps.
Please help. Best regards

unsigned int tileArrayLength;
/* Find size of tile array - note in future tools versions this will be available from platform.h */
asm volatile ("ldc %0, tile.globound":"=r"(tileArrayLength));
tileId = get_tile_id(tile[4]);
read_sswitch_reg(tileId, 6, pllVal);
pllVal &= PLL_MASK;
write_sswitch_reg_no_ack(tileId, 6, pllVal);
wait_us_reboot(3000);
