6. Uncomment 3), comment out next test case
7. Run test
8. Test PASS

cc @ARMmbed/team-cypress Please review

@0xc0170 This issue is reported by Cypress team.

[0xc0170]

I don't understand where is the issue. What should be expected and what is failing in the init phase? can you clarify more details as you already looked at the failures.

@0xc0170 I run analogin tests.

main.cpp contains two test cases:
Case cases[] = {
// This will be run for all pins
Case("AnalogIn - init test", all_ports<AnaloginPort, DefaultFormFactor, analogin_init>),
// This will be run for single pin
Case("AnalogIn - read test", all_ports<AnaloginPort, DefaultFormFactor, analogin_test>),
};

Expected is to PASS 2 test cases. First passed, second failed.
When I run them separatelly - each of them passed.

@maciejbocianski Is this similar to what you fixed in i2c - missing free function for analogin ?

[mprse]

Probably because the ports are already initialized when second test case is running and re-init fails. We don't have free() function in the Analogin HAL API. The driver should allow re-init I think.

[yarbcy]

@mprse Are going to add "free()" or expecting some actions from Cypress side ?

[mprse]

I don't have information about adding analogin free() function to HAL API. Maybe this should be considered. I suggest updating the Cypress driver to allow the reinitialization of the peripheral.

[yarbcy]

OK. I am goint to investigate this on Cypress side.

@mprse I also see similar issue with SPI. Should I creare new issue or use this one?

new issue would work (as its for SPI)
