### gpio_all_i_user 
```configure all gpios as user input using automatic approach firmware and check them``` 
### gpio_all_i_pu 
```configure all gpios as mgmt input pull up using automatic approach firmware and check them``` 
### gpio_all_i_pu_user 
```configure all gpios as user input pull up using automatic approach firmware and check them``` 
### gpio_all_i_pd 
```configure all gpios as mgmt input pull down using automatic approach firmware and check them```

```configure all gpios as user bidir  using automatic approach firmware and check them``` 
### gpio_all_o 
```configure all gpios as mgmt output using automatic approach firmware and check them``` 
### gpio_all_o_user 
```configure all gpios as user output using automatic approach firmware and check them``` 
### mgmt_gpio_out 
```tests blinking of mgmt gpio bit as an output``` 
### mgmt_gpio_in 
```tests blinking of mgmt gpio bit as an output``` 
### mgmt_gpio_bidir

# housekeeping
### hk_disable 
```check Housekeeping SPI disable register is working``` 
### hk_regs_rst_spi 
```check reset value of house keeping registers by reading them trough the spi housekeeping``` 
### hk_regs_wr_wb_cpu 
```bit bash test for housekeeping registers``` 
### hk_regs_wr_spi 
```write then read(the written value) from random housekeeping registers through the SPI housekeeping``` 
### hk_regs_wr_wb 
```write then read (the written value) from random housekeeping registers through the firmware but without using CPU, the SPI and system regs can't be read using firmware so the test only GPIO regs inside housekeeping ```
