Tool/software:
Hello,
In my board, I have a connector to access the SCI-A for bootloader on pins
GPIO28/SCIA_RX
GPIO29/SCIA_TX
I want to use this connector to communicate with the connectivity manager using the CM-UART when the application is loaded and running.
Unfortunatelly, there is no Pin-Mux options on those pins to connect to CM-UART
| Pin | Name | Selected Mode | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 |
| V11 | GPIO28 | SCIA_RX | GPIO28 | SCIA_RX | EMIF1_CS4n | GPIO28 | OUTPUTXBAR5 | EQEP3_A | SD2_D3 | GPIO28 | EMIF1_CS2n | GPIO28 | EPWM15A | FSIRXH_D1 | ||||
| W11 | GPIO29 | SCIA_TX | GPIO29 | SCIA_TX | EMIF1_SDCKE | GPIO29 | OUTPUTXBAR6 | EQEP3_B | SD2_C3 | GPIO29 | EMIF1_CS3n | ESC_LATCH0 | ESC_I2C_SDA | GPIO29 | EPWM15B | ESC_SYNC0 | FSIRXH_CLK |
- Can I use the in/out/xbar or the CLB module to add this possibility?
- How should I set it up?
I have my CM-UART currently assigned to pin 84/85
| A11 | GPIO84 | UARTA_TX | GPIO84 | GPIO84 | SCIA_TX | MDXB | GPIO84 | UARTA_TX | GPIO84 | ESC_TX0_ENA | MDXA | |||||||
| B11 | GPIO85 | UARTA_RX | GPIO85 | EMIF1_D0 | GPIO85 | SCIA_RX | MDRB | GPIO85 | UARTA_RX | GPIO85 | ESC_TX0_CLK | MDRA |
Note: I want to avoid programming the OTP to change the default SCI-A bootloader, because I want to avoid having JTAG adapters (e.g. XDS110) in the production line. Ideally they would need just normal USB-UART adapters to flash the FW.
Thanks in advance.
Kind Regards
